What do you mean " built " ? If you plan on having alot of horses and racing it around, you will need something stronger than the th350 thats in it. you will also have to change out the rear shafts to bigblock. If its an early 76 then the radiator that is in it is good if its in great shape and all the seals are good. Change out the front springs to big block. Might need a taller hood depending on your intake. Exhaust either needs to change to 21/2 or add bigblock headers and sidepipes. The oil pan that is on the 1991 motor might not work with the P/S system if it has p/s. The 1991 is throttle body system, so if your staying with it, fuel pump and wiring upgrades are needed. Then there is a question of the accessory system and what your going with.
