    I can get a 88 blazer with tbi cheap but the motor is junk my question is can I use the stock 400 from my rotted out 79 if I use the late model heads and drill the steam holes and put them on the 400? or will it require more fuel press and high flow injectors.

    We just put an 89 TBI from a 350 on a 77 400CI. Kept the 400 heads. Just redrilled the middle 4 bolts on the TBI manifold and bolted it up. Runs great.
