Got the S10 all torn down to pretty much just fenders and cab. Took the 2.8 out and it looks almost like you could drop a V8 in it would just sit farther back because of the frame mount setup. I didn't know if anyone had any info on this. I figure if it could be done I could get a V8 transmission from a 4wd pickup and bolt it up to the NP207c transfer case without having to change much. It would also give more clearance for headers. The cab is jacked up and sitting on some 4x4 pieces of wood right now so I think I would have to put about a 4" body lift on the truck if this all would be possible. Ill post pictures tomorrow if the weather is good. I definitely want to keep the 4wd.
