LS engine and THM400 trans?

[thedude327]

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.

Looks about right. Mind you that's the all aluminum LS block.
Not the truck LS based Iron blocks.
