I have an 86 Z28 with a stock LG4. I found a good donar powertrain out of a 93 chevy halfton. How easy is the swap and is their and tips or anything on it?

Assuming its a carb for carb swap it will be very strait forward. You cant use the truck trans though without keeping injection because it was an electronic controlled trans

Well I was hoping to keep the TBI injection on the 350. I was debating on if I should use the 700R4 or the 4L60 but Idk. If I kept the TBI Injection how much more dificult would it be?
