This has probably been asked, but can I use my 305 TPI unit on a 350 that I am building? Do I need differant injectors? What else do I need to change? The 350 is going into my 91 Z28 and I will be using the stock 5 speed.

The TPI unit is the exact same for both engine. The 305 injectors are 19lb/hr, and the 350 units are 22lb/hr. You'll want new injectors eventually, but for now, you could run the 305 injectors at a higher than stock fuel pressure and do fine.
