My '88 camaro came with the 305 LO3, and the previous owner put in a 350, and hooked it to the Stock L03 Controls.. Can my fuel pump keep up with the 350? or is the 305 ECM only giving my 350 enough gas to power a 305?

Basically, My ECM Thinks theres a 305 under the hood correct? Now how can i get it to know theres a 350 now?

 

Go to a TBI 350 truck(Auto if yours is automatic, manual if yours is stick), pull the ECM and Injectors. Go to you local parts house and pick up a 350 Knock sensor. Install the parts. The fuel pump should be fine for a stock 350. The stock 350 really doesn't make much more HP than the 305, but makes a good amount more low-mid range torque. Your car may actually feel slower up top, when in reality it is quicker.

 

I can get a 350 4bbl ECM.. is that the same?
