Is it possible you can update us when you get it on. I would like to know about your gains, since I have basically the same mods as you.

You should be able to use the LS1 injector o-rings to get the rail to clear. Instead of the adapter kit from FAST you can use a washer to bridge the gap where the rail doesnt meet the intake. It will save you some cash and it will still work.

I have the LS2 corvette. The motor and fuel rail is the same. I just installed my fast with LS1 injector o-rings and used washers to hold the rail down. I know the holes dont line up but with the right size washer it will overlap the tab on the fuel rail.

I have a FAST 92. The bolt pattern is the same as a 90 because they were made for the LS1. Im telling you for 8 dollars in hard ware and the LS1 injector o-rings you can hold the fuel rail down and it will clear the manifold. If your picky about looks order the 80 dollar adapter kit.
