will be going into a cammed lq4 in an NBS Silverado. Willt he fit directly or would the rails need to be modified??

 

When installing the Ford Green Tops in trucks before I had to just make slight modifications to the fuel rails, just enlarged the holes a bit where the rails mount on the intake to give a little better angle with the way the injectors set in there. After that I would just have to use some spacers, longer bolts and washers. Works out well and really is easier than it sounds. Also will just have to tweak the crossover pipe (if applicable) that runs over the top of the intake as well but that's no big deal either.

And of course you will just need the EV1 style electrical connectors also.
