Early 305 to 350
OK, if I want to put a 350 under my TPI, I can get bigger injectors (or raise the fool pressure), and change to a 350 chip. BUT...the set-up in my car is from an 85-87 (with cold start injector), when no 350 was available from the factory. Is my only alternative to get a custom chip burned?

1) 22# injectors
2) 1988 GM chip for a 350 (cold start Inj.)
3) AFPR to lower the 305 FP from 48 to 41PSI
