L76 Injectors And Rails I've heard about the different length injectors, thickness o-rings, etc., but what I haven't been able to nail down yet is can I use my LS6 F.A.S.T fuel rails and Ford 42 lb. injectors on a bare L76 intake? I've included the part numbers to the combo I want to use. Y'all be easy on me, this is my first post.

The injectors will work, but you'll need Katech's adapter kit which has thicker o-rings, because the bosses/holes in the L76 intake are bigger. As far as the fuel rails working, I'm unsure. That's dependent on the locations of the mounting tabs. If the tabs are in the same place as the LS1 rails, then no they won't work. But its not that big of a task to fix as they would need to be relocated slightly.
He was asking if the FAST fuel rails would work on the L76 intake. My guess would be no because the FAST fuel rails have a slot on the bottom side of the rails where the aluminum spacer/mount fits, and there's a bolt/screw that threads into the side that attaches the mount to the rail. Then another bolt/screw that is used to fasten down the rails to the manifold. The mount positions are the same between the LS1 and LS6, but are different than the L76.
The LS2 rails will work on the L76 intake. I have verified this. If you buy the L76 intake kit, it comes with LS2 rails and LS7 injectors. I put the LS2 rails on the FAST intake and the mounting tabs don't line up with the threads/taps on the manifold. So that's what leads me to know that the FAST rails won't work on the L76 intake.
