So I put a sbc 305 into my 2000 s10 after the 2.2 blew and it came with a th350 and I had previously put a mini spool into the rear end. Earlier today I laid my foot down and the trans broke, looked under the truck and the driveshaft wasn't spinning. I pushed the truck and I looked to make sure the driveshaft was spinning, but nothing. So I already have the mindset that I need a new transmission and differential, for the transmission I am contemplating on a 700r4. Anyways, my question is what rear end can I easily put in the truck that will hold up better than the 2.2 rear end? Does the ford 9" easily fit or does it require quite a bit of modification?
