Hey i had a 91 s-10 that i put a 350 in it had airbags on it which made it tougher to put in but i found that a 700r4 tranny bolted up would work but just wasn't really reliable for the power a turbo 350 is the better option... new distributor and intake manifold i go an accel high voltage hei supercoil distributor. the intake i used was off of an older 350 i ended up having to slot out the center bolt holes to make it work they still tightened up and sealed the motor was out of a 93 van and the intakes were different it was a throttle body motor... exhaust manifolds come out of a 89 suburban they were tight to the block and instead of running down the side of the motor they tucked in tighter to the valve covers... had to put an electric fan on it in front of the radiator but behind the grille... its a tight fit and its alot of work but in the end i found that it is MORE than enough motor for the truck... i ended up motor and all spending roughly 12 to 1500 dollars for everything... i sold the truck shortly after cause the r4 tranny just won't hold up long if you run it hard i wish every day that i'da put the turbo 350 in it.. any other questions just e-mail me at
