do any of the LS engine injectors work on the LT1

 

The stock LS1 injectors would flow about the same on the stock lower fuel pressure of the LT1.

 

why i am asking this is that i have some 26 lb injectors frome a corvette i was wanting to no if they would work on the LT 1

 

The LS1 injectors are flow rated at 58psi, and the LT1 injectors at 43.5psi. That means that if you run a 26 #/HR LS1 injector in a lower pressure LT1 fuel system, is will only flow 22.5 #/HR. They will fit into the LT1, but you would either need to raise the fuel pressure to get them back to the stock injector rating (24.9 #/HR) or have your PCM programmed with the smaller injector size.
