I have searched on this topic and everyone says they work but will flow less because of the pressure.
The problem I am having is my harness clips that go to the fuel injectors are never gonna fit on these LS1 injectors I,ve got, do you have to splice in new connectors as well?
This may be too much hacking for me ( thats a laugh) but I may just have to sell these and go with some LT1 injectors.

 

You probably have something else. LS1 injectors work just fine with the LT1 harness.

 

unless they switched connectors on the later ones, but I doubt it

 

Are you talking about the retaining clips? If so just take a dremil and wxtend the groove all the way around. If you are talking about the electrical conector then you don't have LS1 injectors because they are exactly the same. I have used LS1's several times with no problems other then te injector retainer clip and that was a simple fix

 

Great.........Thanks guys.
Gotta figure out what the hell these are now so I can sell em.
