I do believe the stock fuel rails will work and FAST claims a 25hp gain over stock. I would like to hear from someone about this as well. I believe skeet on here is running one on his truck.

Skeet is using the LSXr intake, not the rt version. I don't know about the rails, but I doubt the stockers will work. FAST is pretty good about making it to where only their proprietary stuff work work correctly. As far as gains go, the LSXrt didn't show much gain on anyone else's dyno except FAST's. Not hating on them because the 102mm car style intake showed serious gains on skeet's stock cube motor. Just haven't seen anything impressive from their "truck" intake, definitely not for the cash you're going to shell out for one.

Yeah my wallet would be alot better off just getting a TBSS intake vs $1000 for the FAST..

Just wondering, since you built a bigger cube motor why you wouldn't want to use the LSXr version over the truck one?

FWIW, FAST sells a kit so you can adapt the stock rails to the new intake.
