Hi im new to this forum, I just bought a 89 rs 305 and Im looking to put a 350 in it. A year ago i had a 89 firebird formula tpi, the car was totaled out and i saved the motor and tranny. The motor was just rebuild and so was the trans. Its a strong setup. I wanted to pull the tpi unit off the motor and put a eldbrock performer tbi intake and get a 350 injector pod, and get a custom prom to run the 350. I have a pair of eldbrock header w/air. So the question is, I wasnted to know if i needed anything else for the 350 i know almost all the sensor are interchangeable. I think i need a 350 knock sensor due to the 305 piston size is smaller than a 350's. I shouldn't have a problem with this swap will i?

 

The only problem i had the the t5 flywheel, since my 350 has a internal balanced crank, so i just took the flywheel from a 62 'vette. Other then that direct swap.
Too bad the injectors and stock headers really tames it!
