dont forget to swap gas tanks, or clean the diesel one out completely for gas. The tranny originally behind a diesel has a different governor to shift right away as opposed to gas motors that rev a little higher. It probably has hydroboost, so keep that and swap to the new small block with factory small block brackets. Save the radiator hoses as they are long and expensive. Not sure on the motor mounts, but i assume they swap right over, i know bbc and sbc are the same for that era truck. Hook 12v ign straigt to the hei or coil +. pretty easy swap if you have all the sbc parts to make it run.
