the holes where the fuel rail bolts to the intake will not line up and the injectors are different from the ls1 rail to the ls2 rail. will it work yes, will it be correct no. where are you located? If your close I will trade you a ls1/ls6 rail for your ls2 rail

why are you getting rid of the truck intake? If you have room for it it makes good power.

The fuel rail in you link is for a LS2 C6/GTO intake. Its NOT directly compatible with a LS1 or LS6 intake. I don't have a lot of experience with the pro flo intake so im not sure if it will work with that set up. My guess would be probably not perfectly and it would be best to call the manufacture and get their rec as to what fuel rail to use.

This seems to be the best post on rails/injectors I've seen, I'm doing essentially the same thing 4.8 retrofit into 74 nova, not going crazy big on this build as I'm new to the ls swaps. I've got 4.8 and ls1 intake, and dont wanna swap my tank yet so im doing inline pump which requires returness fuel system. i found a buddy with a great deal on an ls6 rail from a Z06 with 28 lb injectors, are these injectors way to much for a 4.8? If so I could switch inkectors since I've got a good enough deal, but will the ls6 rails work directly with my ls1 intake?
