Heres the scoop on my delema. I have a 91’ Isuzu Amigo that I already swapped a GM 3.1 motor and 5spd trans in. The truck now has a rod knock. I can pickup a LT1 for a decent price complete with a entire harness and ecm off my buddy. The trucks 4wd and I would like to keep it that way. Would the LT1 bolt right up to the 3.1 trans? Or will I need a different trans to fit into the truck? I am not worried about the rest. I just want to get the drivetran part done. ---

It wont bolt to the tranny- different bellhousing. The 3.1 is a 60\* motor and the LT1 is a 90\* motor. Even if it did the v6 tranny wouldnt be able to handle the torque of the v8. Id look for another 3.1 or a 3.4 out of a Camaro. A 3.4 is just a bigger 3.1 which is a bigger 2.8 and it will bolt up to the same tranny. It would be like swapping a 305 out for a 350. ---

Just wanted to make sure before I picked up the LT1. ---

Cheaper, same swap and more power. You can pick up a low milaege 5.3 (20-40k) for around $500-700 and the T56 will bolt right up…and all LSx parts are interchangeable with it. Get the best of best worlds. check out the Hybrid section on ls1tech. Theirs a shit load of guys that have done the 5.3 and LS1 swaps into S14’s.
