Hi all
I am at the evaluation stage of power train swap in my 99 VX.
Engine will be stroked 383ci Corvette's LT1 (400-450HP) and GM transmission 5speed and xfer case complimented with F/R lockers.
I am interested in your opinions about this setup.
Please also comment on sudden availability of complete mint VX power train and number of auxiliary components.
Thx

PS: my other car is modified L98 Corvette

Um.... best of luck, I guess. I think the engine and drivetrain are the easiest of your mods on that project. Why not just drop the VX body on a Vette chassis..... ;)

Thx for constructive reply WormGod
C4 Vette is a bird cage frame RWD, it wouldnt work to top it with VX body........
SBC has been dropped into Austin Mini, Range Rower, Trooper II and Fiero to mention few, mostly it worked fine.
You are right WormGod to bring LT1 to 450HP would be the least of the problem. What makes this a bit easier is that VX does not have a single computer for engine, tranny, TOD etc. That allows GM ECM (the computer) to be a stand alone unit. The VX ladder frame with addition of few gussets should be stiff enough to handle the torque.
Transaxles well I dont know, to have them locked and flooring it on uneven surface, an axle or two might give up.
Word of wisdom: VXLT1 shall see many BMW X5 4.4i in it's rear view mirror

If you know anyone in the auto salvage business, you could have them look for my totalled VX with 6755 miles on the drivetrain. E-mail me if you'd like any additional info.

This idea has been talked about and kicked around by several VX owners. When my engine blew in Nov. this year I looked into the possibility of dropping a GM crate engine into mine instead of using the factory Isuzu motor. I was only looking to use the GM engine and not the drivetrain as you are suggesting. Here are some things to consider:
Engine placement & mounts--lots of custom fabricating
Wiring--not as easy as just replacing the ECM and factory wiring
Accesories--custom mounts for AC, Alt., and oil pump
Now for the tranny:
Again custom mounts and location
Custom drivelines
This project is borderline insane. Not to mention the custom fab and wiring headaches, the cost is could be more than your VX is worth. Easily 10-15 grand USD and you're in Canada. If you go through with this swap my hat comes off to you. Just keep all notes for the custom made parts to make this available to anyone else that would like a different powerplant. Good luck.

Nothing new here, plenty of big V8 tansplants have been done in Troopers. Imagine the surprise of the luxury SUV crowd when left in the dust by a lifted Gen1 Trooper! If you pull the project off you'll just be adding the style of the VX, which you'd expect to perform as it looks. You want REAL power? There's a guy here in town that's got a Cummins multi-fuel engine and drivetrain from a military 2 1/2 ton stuffed in a Gen1 Trooper. Put that in your VX!
If you really want to impress this crowd, do a turbine conversion.;Do;

I know I don't chat hear much, I really just kinda read around..
Anywho, this swap isn't entirely out of the question..
It just depends on what you can do yourself.. My dad is a welder, as well as an electronics specialist. I learned a lot under him in the world of electronics, having done the whole "son goes to work with dad and dicks around" thing for a couple of years, and then actually did work with him for about 2..
What I'm saying is, if I was doing this, my dad could fabricate the mounts, and we could wire it up together.. thats the majority of the problems taken care of right there. It might not cost this person as much as you'd think.
I think it is possible to put nearly any engine in any vehicle, one way or another. It just takes thinking outside of the box at times..

Not too sure why this guy is being dogged on. It seems like he is pretty knowledgable, and... although a V8 swap in an Isuzu may not be new, it would be a first in a VX.
Pretty sure if it was someone who has posted a bit on this board doing the swap there would be a lot of interest.
If this guy is serious, then I am definitely interested in seeing the progress.

I agree - let's not dog this guy, he's a pioneer. If you want to do it badly enough, it can be done. I used to have a TR6 with a 351 Cleveland, built by a guy who did all the work himself. If that can be done, this is surely a doable project! I for one would love to see this happen!
VX_PA
12/31/2003, 08:48 AM
No doggin here, I'm just a realist and trying to offer some advise. I'm all for this set-up as I have no confidence what-so-ever in the Isuzu engine that I just put in my VX. If this guy does this swap I'll be right on his coat-tail once the custom crap is figured out. Unfortunitely he will be bearing all the upfront costs for the custom designs, after that this swap would be affordable for anyone. As I mentioned, I considered it but didn't have the doe or the time to make it worthwhile.
Go for it, I'm very interested!! As I'm sure others here are too?

Hey Raque,
Funny, I owned a TR7 with a 351 Cleveland mounted in it. Same story, guy I bought it from put it in there himself. Of course, back then it was a lot easier to make stuff like that work (no computers to fool with). The Triumph I owned was so light it would whip around in a heartbeat with a little throttle - main reason I got rid of it.
I hope no one thought I was dogging the guy - just trying to inject some levity in there. I applaud anyone who has the time and compunction to do a major overhaul like an engine mod. It will be interesting to see who does it first (may have already been done and we just don't know about it).

My reply wasnt exactly "constructive" as it was more sarctastic. ;) But, I see that you are quite the gung-ho project guru, so I say go for it. Any mod you make will surely be a make or break for your money (MAKE is, of course, the option that I hope you lean on).
As for anyone dogging this cat, I dont think that's the intention. Anyone that appears to be doggong is just adding the "hard bet" and telling him it is a tough task ahead for him. Trust me.... I think any of us would love to have an LT1 shoved in our VX's belly.
My main quirk is handling. That much adrenaline going through that tight wheelbase and suspension, you may very well land that thing on it's roof in a ditch. Lot's, and I mean LOT'S to think about. :D

I think it would've been a well received-talked about post if the project were done and the pics were posted. Instead...it's an odds on favorite to end up alongside the endless posts about Northstar conversions, electric motor conversions, Hydrogen fuel cell conversions, blah, blah, blah.
I would welcome a bright, enthusiastic "realistic" attempt at upgrading the VX to a new Axiom Direct Injection 3.5L with Alpine blower and PV exhaust....
Now that would be awesome!!!!!!!!!!
P.S.---Sorry if I seem too sarcastic here...kudos if you follow through with it....I just doubt that it will ever happen.

No doggin' here either, just IMHO there are better options. With the VX's SWB that LT1 is going to kill handling.
Although range would be limited by fuel consumption the turbine conversion would be awesome! Although John's hyperdrive suggestion wouldn't be bad either...;eekg;

Hey, I'd love to see it, and love for him to still want to talk to us if he ever does go through with it.
Had a FX35 wanting to play this afternoon. Kinda wish I had tried it just to see how far behind he left me (280hp, 270 ft lbs torque) and if I could have at least made it slightly interesting. He's probably online right now trying to find out what the heck that thing was and if it could've beat him. LOL! Hey, with a S/C it would be real tempting (probably would lose, but more interesting). :-)

Hi Guys, thx for the feedback some of it is good and some of it belongs to Britney fans forum.
VX can crawl rocks and outrun most of similar vehicles when on the pavement and that is what makes it so unique and a good platform for this type of conversion.
-Where diesel would really shine in say Trooper it would just kill the characteristics of the VX. To put in Axiom engine, why? I got Isuzu engine in it already and it runs like Swiss watch, those few HPs can be easily gained by opening the intake tract, regrinding camshaft lobes for more lift and increase fuel pressure. To supercharge without beefing up the vulnerable bottom end is....
-Turbines, fuel cell etc. I don’t know much about but I know my SBC.
Anyway LT1 it is!
LT1 is high torque, high revving responsive engine and a good choice of heads, camshaft and CPU tuning would only enhance the VX’s.
LT1 can probably by position lower than 6EV1 since it does not have skirt and elaborate bolt on oil gallery/brace.
Over all I am not looking for your approval to do my project but like I said at the beginning of this thread it is your intelligent opinion that I am after.
Thank you for valuable input.

I don't know how you define realistic, but even if it's not, a lot of us do daydream about BIG power in our little trucks. I remember a great Car&Driver project where they installed a second engine in the rear of a Honda CRX. They successfully doubled the horsepower with no drawbacks other than a little additonal weight and zero cargo room. My point is anything is possible and if this guy succeeds we all have one heck of an amazing option to think about in the future. If not, it was just a nice dream and a little laugh for some.

Anyone who did this would be my hero - I plan on keeping my VX long enough that EVENTUALLY I'll make it a real beast. Until then, I must live vicariously through others. In my mind, a VX shouldn't ever be allowed to die - it should be made damn near immortal. :-)

I've been seeing and hearing quite a bit of fun being poked at the expense of the "Newbies" as of late. It matters not if a person is new or old to this site, everyone should be treated the same. Albeit, there are some that have a more intimate knowledge of the VX but, everyone has a certain spirit that lends to the overall quality of this community. Most people have ideas and are too afraid to speak out for fear of ridicule. I tend to believe, say it aloud for you never know whom may be able to help you accomplish what you wish.

2004 Isuzu Axiom Direct Injection 3.5L is 250 hp.
1999-2001 Isuzu VehiCross 3.5L is 215hp.
That is 35hp. increase to start with. Add Blower and better exhaust and I figure close to 300hp would be the high-side of your increase. It wouldn't be easy...drive by wire throttle conversion...swapping computers...but, engine would of course fit and you would maintain your weight balance thus handling wouldn't suffer. I don't think you would have to beef up the bottom end for a mild blower like the Alpine...no one here has beefed up theirs...Of course this is uncharted territory and if you really know engines than by all means beef it up... It wouldn't be comparable to a Keith Black Hemi but I thought it to be realistic to do. Kind of like updating/upgrading our VX to todays hp output. Version 2.0 if you will! I also saw this as perhaps a route for someone experiencing motor failure. Instead of dropping in another VX 3.5L...Perhaps upgrade at additional cost?
I support you if you're serious and wish you the best of luck.
I want that motor... Direct Injection 3.5L, that motor is NICE!
Drops the 0-60 a full second down to 7.6 and 1/4 mile @ 15.4@90.9, That is probably as quick as my VX with the stinking S/C on it.
Well when my motor goes I think I'll get that one.
GOOD LUCK with your LT1 motor... will be AMAZING for sure if you can pull it off, Guess if you do that will be my next motor :)

Few good points Jolly Roger VX’er and others
Let’s divert from the subject of LT1 for a moment.
I am not trying to replace a faulty or marginal engine. If I decide that the project is worth executing this premium used engine and other guts will be available to my fellow VX’ers and late model Zuzu owners.
The VX’s original 6EV1 is a high tech engine with unbelievably flat output across its full rpm range courtesy of selectable length runners and cloverleaf combustion chamber. It will easily outrun supercharged Toyota TRD truck and many others.
The 35HP+ can be gained on VX by easy mods that I mentioned earlier in this thread and if one wants to rollup sleeves and start degreeing cams, add centrifugal blower/intercooler preserving benefits of existing runners, computer (PCM) tuning etc. would bring the output conservatively well over 300HP! So now we are approaching barrier of 100HP/liter ratio and that is frightening because reliability and maintenance. At this point I am not addressing rest of the power train where torque converter stall speed needs to be lowered and few internals replaced…..
I am not familiar with the Axiom power train but 30extra ponies and direct injection decal would not make it my choice, furthermore that new engine is not around long enough to proof itself. Isuzu is pulling out of passenger vehicle market in its’ present form so good luck with spares and any support on that engine!!!
Thx, VX922

I like the idea of an LT1... but of course, my first thought of a similar swap came from my F-Body experience... my V-8 choice was a little new technology and a little lighter weight... my choice was the LS1. I have thought and daydreamed of this a few times... and since I am in the crappy position of NEEDING a new motor, it was tempting to shoot for it... but I don't have any good sources for complete motor and computer/harness package. That of course leads into the transmission problems... my though... why not go with something familiar to me... T-56! How kick @$$ would that be? LS1 (340-350 crank HP/ 360 lbs/ft of torque) with a six speed manual trans... the motor would be lighter than an LT1 and I have LOTS of experience and have LOTS of contacts regarding this motor... now if I could just find one for a reasonable price! lol Ok, I'm gonna quit my dreaming cuz I'm sure its not gonna happen for me anything soon... then again... lemme go chat with a friend of mine... see if he knows where a motor is...
Good luck with your conversion... let us know what stage you are in... if your moving forward or what...

I still would like to hear groups opinion on drivability, reliability issues, manual vs. auto, overall market value of VXLT(S)1 etc. Remember I consider this to be innitial project stage only! I have to evaluate it from many angles since I am donating mint shape VX plus the cost of the components and some yarded out work.

It appears weight wise the LS1 would be the logical approach. It's a lot closer to the weight of the 3.5 engine we currently have. The problem with that engine is the cost. I wonder if anyone here has any connections in the salvage industry? Anyone??
It would benefit all here to support this swap attemp. If these guys can pull this off all the ground work will be in place for anyone else to follow. We're talking real deal power here, isn't that what we all dream of?
Good Luck fellows. If you run into any technical problems, post them and I'd be glad to help find solutions to them. I'm sure others here would be willing to help too.

Rotary, good powerplant, but no torque. If you were looking for high speed or top end it would be good. For off-road it wouldn't be a viable option, power comes in only at high rpm. Still not a bad idea, can you say "TWIN TURBO".

My dad works at a salvage yard up here, not sure if he could find an LS1 though (not too many sport cars up here in AK). A lot of my friends are driving cars that were "totalled" and they got a great deal on them through my dad. One of my buddies picked up a 97 Blazer w/30,000 miles for $3,000 and all that was wrong with it was a broken window and a dent in every panel.
Let me know if you guys need anything and I can ask him, but shipping would be expensive. I can see what I can do though, would love to see this conversion happen!

01/02/2004, 09:32 PM
OK, my first obstacle has been cleared... the need for plasma cutter and good welder... along with personel to run them! My bosses best friend will be willing to make some custom motor and tranny mounts... so I can get the motor and tranny in place... thats the easiest part of the job IMO.
The first technical problem that I had hoped to find a cure for today was the transmission... the easy route for this project (with LS1) will be with the 4L60E transmission... the question lies with whether or not I can mate the TOD transfer case to this tranny... or should I say, how HARD it will be to do. I personally think this will be the toughest problem... many others might suggest a standard transfer case, but I would like to retain my TOD... just far superior IMO. This would probably end up pushing the transfer case slightly rearward (which might offset the f/r weight distrution with the added weight of the motor in the front)... so this will require custom length drive shaft and front prop shaft. Again, I know of local tranny shops here that can and will do this service reasonably.
OK, so I pose my first question... can we mate a 4L60E transmission from an F-Body, Vette or truck to the TOD? Of so, what kind of custom fabrication will be needed? Any suggestions of good sources of info? I will be calling a buddy of mine tomorrow... his bro-in-law is a transmission specialist... at least in the old-school muscle department... but he might have some answers.
Again, I think the electronics department will be fairly easy... of course, if we find out that the ABS system runs through or in the main engine PCM... that could cause a problem... then again... WHO likes ABS?! lol Don't need that! lol Unless of course its easily retained.
I'll be reading some pages... doing some research for awhile... If you want to chat about this and you use AIM or AOL's Instant Messenger, you can usually find me logged onto it as GiveWedgie... however, sometimes I am not here... even though I am logged on... so if I don't answer, leave your email address and I will write back later.

I have dealt with them before for OTHER Firebird parts during my Trans Am craze (three WS6 drop top's and one non-WS6 drop top)... anyway, I know they will have the motor and trans... as well as the computer... the retro harness like I said can be bought through Jeg's for $499.

Thanks for the info... I checked their website for info... I have sent them an email and will call them on Monday... I did however notice a blurb on their site that stated, "NOTE: WE DO NOT DO ANY CAR CONVERSIONS, AND WE NO LONGER DO ANY CHEVY LUV OR ISUZU TROOPER CONVERSIONS." so I have no idea what to expect. Was there some kind of Trooper conversion that was pretty common? I'm hoping that a 4L60E tranny is common enough in larger rigs and that maybe by a stroke of luck the TOD has a bolt pattern that is used on other transer cases that maybe they will pull it together. I think this is the hardest hurdle to clear. If they are able to provide the part I need... we are in business. Thanks again!

Somewhere down the line you'll have to find u-joints that will mate your rear driveshaft to the isuzu diffy. Front too, if you end up changing t-case. Universal frt. engine mounts used to be easy to find, the trans may need fabbing. I think I recall seeing plastic mock-up blocks that you can buy, to use as a quick tester to see if it will even fit. Either that or you'll have to come up with some kind of block just for test-fitting. I'm wondering how the accessories etc., will fit with our (low-profile?) hood. Also, depending on what body style the engine came out of, the accessories have different mounting locations, at least they used to between vette, f-body and caprice.

I'd be willing to bet they are covering their a$$e$ of any liability. The way this nation/world has become so sue-happy over everything means people/businesses no longer go the extra mile to help in anything other than what "appears" to be legally black & white with virtually no chance for legal reprisal.
They probably got burned/nearly got burned/seen someone else get burned on a prior conversion and are not interested as the profit doesn't justify the risk.
But as SGT. says.............BE NICE!!!!!!!

I hope to be able to retain my TOD partially for that reason. If I keep the stocker, worse case scenario is that I might have to shorten the rear drive shaft and lengthen the fron prop shaft. This is assuming that the 4L60E trans is physically larger/longer than the 4L30E trans. I have a master welder/fabricator at bay for any special mount (engine/tranny) making. He has built a couple of HUGE jeeps... jeeps that would be nearly capable of driving right over the top of my VX! ;eekb; Anyway, I still think that mouting is gonna be the least of my problems.
Yeah, I will be VERY nice to Advanced Adaptors... If they can help me adapt the tranny-transfer case, I think this project is a go! Once I get their POSITIVE input tomorrow... I will be locating an engine/tranny/computer. I think I might be crazy... whatayathink?!

Drive shafts should not be a problem there is a great number of OEM components to built just about any shaft. I would most likely go with custom manufactured aluminum or composite shafts and make old shafts garage sale item.
Precise shaft balancing is mandatory becose 4.3 axles ratio.
TOD might be a week point of this setup, I can see burned clutches already! I think that complete manual xmission out of a GMC 4x4 together with manual hub locks might be a better choice.
In this conversion the overall gear rations need to be examined against torque curves of the LT1.

Most anything you might need is available in the aftermarket as a direct fit or with modification. However, in this day and age you have to be mindful of your emmission laws. If you have mandatory tailpipe testing in your area, or the prospect of it being put in place then your VX could be illegal to drive on the street or license. According to CARB rules which most states and feds copy, if the receiving vehicle is covered by emission regulations, no matter how clean it is, before it can be tested the swap has the meet several critiera. First the new motor has to be the same year or newer than the vehicle. Second the motor needs to be of the same family as the veihcle. I.E. no Ford into Chevy ect. Now, with the Hombre being sold as an Izuzu, a 4.3 would be legal but not another GM motor not sold as a Izuzu.
If you can get past all this, then you go to arbitration and are then at the whim of a bureaucrat. There is also this old thread. Good luck.

You might be!;)
If you have the opportunity, try to look at the different blocks with all accessories bolted on. Some keep accs'ys. low and others high.
Sometimes you can get around the emmissions by claiming "off-road or show vehicle". Usually you have to prove it by having that kind of insurance and/or appraisal . If you drive it daily, keep a current list of car shows in the vehicle.

Very good points skunkworks!
The VX in it's present format is not green by any measure. The LS1 (LT1) is clean burning engine as a result of GMC corporate policies from years back. As a result of the conversions I would expect better fuel economy and lover tailpipe emissions. Will it pass red tape regs? I don’t know but I would hate to see all the conversion affords to go to waste bexose some shortsighted government regulation.
In my area (temp. Edmonton Canada) unfortunately no regs at all.
I thing that the challenge is to convert with respect to all DOT, EPA and other applicable agencies. Conduct "bolt on" practices as much as possible and allow for possibility to revert the conversion (thus no cutting torch allowed!).
I hope our respectable friends realize that extends of this project if executed properly, is no less than 12mo for tree shade mechanic like myself. However It would be a noticeable contribution to our micro community to produce a LS(T)1 conversion kit.

Well, no tail pipe sniffing test goin on here in Missouri... nor do I expect it to happen anytime soon. I don't think its gonna be a problem. I also believe that this mod WILL make for a more efficient, cleaner running rig... of course, I could be wrong. I don't plan to bring too much attention to the project when it comes to government agencies... and I DON'T plan to move to CA... so with that being said... if Advanced Adaptors (AA) comes back with a good reply... I'M IN! ;Db; Put me down as a seriously commited (or maybe commitable) fool!
VX922-
How goes your plans? Are you ready to start wrenching?! Keep us all informed. I personally might start wrenching on my rig on Tuesday... even if I don't get the good word back from AA, my motor STILL needs to vacate my engine bay... cuz it aint healin' on its own! It's been three weeks now and I haven't even turned a wrench on it... time to get to work!
Later!

OK guys... I'm kinda committed now... just bought this (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2452145672)! Oh, and I also bought his transmission... and I'm getting the harness that he had later said he wasn't including. Soooo... I guess what I'm trying to say is... I HAVE to get'er done now! lol If not... I'm out about $3250! lol I will start turning bolts today/tonight... and will hopefully have the transfer case and tranny out from the bottom by the end of the week. If all goes well, the seller of the motor will be meeting me on Sunday to make the transfer... stay tuned over the next couple weeks as I start this rediculous voyage! Anyone wanna come to Kansas City and have a little wrench session? I've got a couple different spare bedrooms (bunk beds in one and queen in another) if you wanna come! :D I'll post pictures as things come out... which reminds me... MEMO TO ME: CHARGE CAMERA BATTERIES!
Later!

SWEET, too F'n cool... Keep us posted!

As the saying goes:

I really wish I had ventured down this road two months ago. What an exciting adventure!?! Good luck, let the wrench gods shine down on you.

As far as the 4.3L being sold in the Hombre and the only GM C.A.R.B allowance, you forgot about the 1st gen trooper v6 (2.8L uggggggghhh) gm motor and the 3.1L in the 91-92 Rodeo and 91-94 Pup 4x4s.....anyway...im stuffing a 1989 Caprice 9c1 350 v8 police motor in my 1992 Isuzu Pup 4x2. The wiring harness is soooo simple to swap over its not even funny. You can get a wiring harness for the engine from Painless wiring or Howell Engineering for under 425.00 that is a stand alone unit. You plug in the harness to the motor and to the ecm, throw 12v from the ignition switch to it and VRRRRROOOOMMMMMM. You already have Fuel Injection so the TPI unit already has enough fuel pressure. The motor mounts will need to be fabbed and if you want to keep the 4wd, just need a 700r4 trans or 4L30E (4L60E also) and a GM transfer case and custom length drive sahfts (about $60 each to make). The hardest part about this swap is getting the motor to fit in the engine bay, keeping the A/C, which brackets can be made to adapt the Isuzu compressor to the GM block. Cooling might be an issue as well, but not of this can't be solved, with enough time and effort this swap is not as hard as some people would imagine. Kudos to you and good luck with the swap.

Sounds like a cool project, I have a bit of a soft spot for the LT1 myself. :D I have a couple of defunct 4L60E trannies, one for a LT1 and one for a LS1. The LT1 one is missing the tailshaft housing and both have had parts scavenged off of them. They might be helpful to you as far as mocking up mounts, making bolt pattern adapters, etc. You can have either one of them for the cost of shipping. I can strip the innards out to minimize shipping costs.

Thanks for the offer, but I'll have the engine and transmission in my grubby little hands on Sunday if all goes well. If not, it will be before your case would get here... but THANK YOU very much!

Hi All
I am not fading away, just too busy in other areas of my life. I will start the project sometimes in the spring. Most likely I will go with LS1 and auto transmission. I am bit excited, I put insurance on my VX and it had seen road after two years. It runs like swisswatch, but LS1 will do it really good.

PS: Good luck with your project Coachreed.

Final decision was made. Primarly becose the weight of LT1, significantly lighter LS1 goes in my VX. I am still aiming at mild 400 to 450F/W HPs.

OK, you just HAD to one-up me, didn't you?! Now thats dirty pool! I guess the good news is that once my conversion is done, I can always EASILY pluck my motor out and up-size! ;pb; Or...maybe I'll just find a place to squeeze a Vortech! ;Db; Afterall... there's SOOOOOOOOOO much space left under the hood! lol
What T-case do you plan to use? Are you going to attempt to retain the TOD too? If so, lemme know... I'll hopefully get something done on my adaptor plate over the next week or two... I will have paved that road by the time your ready.
Later!

but how much do you expect the swap to cost? What engine / tranny are you using? What's the effect on the stock tod / computer / goodies, etc.? Is there a thread on this already?
This is ongoing issue with any vehicle that could benefit from more HP, VX is not different.
I was considering V8 option after learning about Isuzu's vulnerable V6.
Since I have a stagnant mint 99VX and most of the means to do the job I decided to go for it. Right now I am porting heads on my LS1 aiming for 400-450HP. I will stay with beefier automatic xmission. Transaxles may stay stock till they snap. TOD needs to be revised since I don’t trust it with the higher torque. Computer and better dashboard will be from the V8 donor, Corvette. The front and the rear transaxles will come from a ½ ton 4x4 pickup truck if needed.
Estimated starting price tag $12,000. The final cost might be offset by the proceeds from sale of VX parts. This project will take at least two years.

My guess is that it was upgraded into a V12 swap project with a 10-years timeframe... so, lets check back in 5 more years :)

That's hilarious... I was reading this thread and saying to myself that I don't remember anyone talking about a V8 for a LONG time. Has anyone ever successfully gotten one in? I remember one vette motor that looked like it was almost wedged under the hood.

I think the closest was Coachreed. He had the engine in and a custom plate made to mate up the transfer case. The VX sits in AlaskaVX's garage awaiting finishing.
