I dont know jack about 3rd gens...but i was wondering what fuel pressure and size injectors are in a 90 350 TPI? I did a search and i think they are 22 lb/hr and 36 PSI?? is that correct?
The reason i ask is i was wondering if my stock 24 lb/hr LT1 injectors will work in my friends car..i know they are bigger injectors, but there is also lower fuel pressure on the TPI, I think LT1's have around 45 psi stock if i remember right.....i was thinking it might equal out. Thanks for your help

Yes Stock LT1 injectors will work in a tpi car.

 

The 350 injectors are 22lb/hr, and are rated at 42psi stock. However, in the real world the actual fuel pressure measured at the rails can vary by several psi. Psi is not determined by the injectors BTW, that's what the fuel pressure regulator is for.

 

Thanks for the info. I wasnt concerned about if the injectors would work (as in fitment) in the car, but more if they would be comapatable with the stock computer tuning for the factory injectors for the TPI.
