I've done a LOT of research into LS engine choices and have come to the conclusion that when it comes to cost vs. hp, the Generation IV 5.3L is the most practical and economically friendly choice.

Ah, yes! I keep forgetting to ask about economy... what do you think would be the gas mileage when applied to the VX?

Sorry, when I said "economically" I meant wallet-wise.

But to answer your question:

If a 2001 Z28 Camaro has a curb weight of approx 3600 lbs, and our VX is approx 4000 lbs... and the Z28 has an LS1 (5.7) with commonly boasted 26ish mpg (other forums)..... then I estimate about 21-25 mpg with a 5.3L in the VX.

That's just pure speculation using sorta-similar variables. The real way to find out is to ask the other forum members that have DONE it, like Wisdom.
WISDOM, PLEASE INSERT YOUR EXPERIENCE!

Also, just to qualify... I'm just a guy with ambition to learn and hopefully soon begin the LS swap process myself.
Not a guru or expert by any means. Just want to help.
