The listing on eBay shows them as 97/98 Corvette injectors. They are actually Bosch injectors. The LS1's injectors had GM part #'s. The 97/98 Vette used GM 12554271, rated at 28.5 #/HR in a 58psi fuel system. The C5 Z06 engine used GM part 12561462, also rated at 28.5 #/HR. If the Bosch is in fact a direct replacement for the GM parts, it would likely have a similar flow rating. If you actually have a 96 Camaro Z28 with an LT1, they will actually flow slightly less (24.7 #/HR) than your stock injectors (24.9 #/HR) when operated at the stock LT1 fuel pressure of 43.5psi.

My reference table shows that injector as rated at 28.55 #/HR, but it does not show the pressure at which it was rated. I'd guess what you have is basically a stock rated LS1 injector, used in the models mentioned above.

 

well this is for my father 95 formula he put a bigger throttle body on and he is putting some headers on and he has a high flow muffler so he got these injectors for free basically and he wanted to put them on. he is have the computer sent out and change for his stuff that he is putting on.

 

He doesn't have to change anything in the computer.... they are the same size as his stock injectors. They will not improve performance in any way. "Free" doesn't make them a good buy.
