I used 60 lb Siemens ( same height as ls1 style ) on billet rails that I had on the stock ls7 intake. On the FAST 102, I had to make new hold down brackets. The aluminum blocks that came with the FAST were too tall.
If you want plug and play, prolly best 2 contact FAST, or Scoggin Dicky. That's were I got mine.

No. I have the 102mm with fast rails. They require a shorter injector than the ls1's and ls2's. Call fast and make sure cause you don't want a loose fit cUsing a fuel leak and possibly a fire. I'm using the fast 50lb injector.

If you want to use a 102mm manifold, LS1 style injectors, and billet fuel rails you need to get 146032-KIT. My brother is running this setup.
You will also need a set of lower injector o-rings that come in the cathedral port intake, but not in the LS3 FAST intake. Your going to have to call FAST and ask them about the o-rings.

They have kits for LS1 (longest), LS2 (medium length), and LS3/7 (Shorty) injectors.
