Default new injector style for LS7?

I tried fitting some LS1 injectors into my LS7 manifold and, as suspected, they dont fit. Does anyone know how big the stock LS7 injectors are, and what our aftermarket options are?

If they are LS2 style, which I have yet to personally look at, SDPC sells an adapter O-Ring. I believe they are the short injectors, so the rail may need spacing as well for regular SVO/Bosch style injectors.

Ill try to find out today

Katech, can you tell me how the bolts come into play, and I guess, how the kit works in general? Also, how can I order it?

The bolts and spacers are to raise the fuel rail for the taller injectors. To order you can call me directly 586-791-4120 x234

Jason, I guess thats where I'm confused. I am using the old style injectors. Will simply using a different size O-ring work, with the old injectors/fuel rail?

If you are using LS1 GEN 3 injectors on a LS7 GEN 4 manifold you need these o-rings plus the spacer to raise the fuel rail for the taller injector.
