Went looking for some weight info and found:
sbc iron approx. 575lbs.
ls engine alum. approx 416lbs.
thm400 trans. approx 135 lbs.
So it looks like using the ls/thm400 combo the weight comes in around 551lbs. and you keep your stock speedo drive and driveshaft length. Plus ls motors can be run to to 6500 rpm w/no drama. Aside from the tci flexplate and maybe a crank spacer, do the LS adapter engine mounts allow for a close to stock engine mounting location? It also looks like a rear sump oil pan may be needed, but other than that. Not too bad of a swap now that there is a distributor kit available for the LS engine and carb style manifolds are available.
