350 TPI going into a 305 TBI car

I decided my Formula was to rotted out and I'm purchasing a rust free 305 TBI car, and was wonder if anyone could tell me what I would need to do to make a 350 TPI work in a 305 TBI car????

Engine and TPI hardware; ECM harness and sensors, and perhaps engine harness; ECM; full exhaust; fuel pump; engine hoses (radiator, heater, fuel - makes sense to just buy new radiator and heater hoses for the TPI application); throttle cables.

Might as well swap over the transmission with the engine. Although the TBI transmission will "work" with the TPI system, there are slight calibration differences.

There may be other details that would depend upon the year and model of each car.
