305 tbi to 350 TPI
Hey group, here I am replacing 305 tbi with 350 TPI. I know I need a new fuel pump but what other important items need replaced? Help please.

Full engine harness with all of the sensors, ECM, 350 knock sensor and module, fuel hoses from engine to chassis, throttle cables, radiator/heater hoses, air cleaner system, exhaust (perfect time to upgrade to headers such as Hooker 2055, and full '86-'90 TPI single cat system on back).
Okay, it will run without the exhaust, but it won't have much power.
What year/type TPI?
