I'm with Chopper on this. You may want to plan on stockpiling some trannys as well.
Plus, before I did too much thought work, I would at least take some close looks at the Mooncraft. That plumbing was pretty damned serious and actually called for a custom made front cladding to house the FMIC. There is no way you are gonna get a TMIC in there unless you go hoodless, heh.
In the end, S/C is the best choice with it's modest power and ease. ya ya, I know, not an easy thing to find, but, occasionally, one will pop up.
Good luck. Can't say it has never been brought up before.
(psst.... I actually prefer turbo myself. :bwgr: )
