Kind of moot, since '84 didn't have any EFI available, and the carb ECM won't run a TPI.
You'll need to get as much of the TPI stuff as possible - harness, sensors, ECM, throttle cables. Accessory harnesses such as alternator will be different, again, best to get the harness out of the donor car. If you have and are keeping AC, you'll need different lines if '88-up.
You'll need the in-tank electric fuel pump. The fuel lines are different. The radiator hoses are different, but just get new hoses.
Unless your '84 engine is the L69 (not very likely), the TPI exhaust is also much better than the carb engine exhaust.
