I currently have a fast 102 with ls3 injectors and ls2 fuel rail. I am redoing my fuel system to run e85. Should i buy aftermarket fuel rails for LS1,2,6 OR LS3? it is a cathedral port intake.

Maybe a better question is has anyone used either of these fuel rails on a Fast 102 [cathedral port]?

I've had good luck with ebay billet rails and fast name brand rails. Either should work well.

Those are the wrong fuel rails for stock style intakes. You need the ones that bolt to the bottom of the rail. Then may have to customize the brackets to make them work, some just have to be drilled. I designed brackets that are adjustable for these rails because we needed something that would not rust. They work with any stock type LS intake and just have make the correct size spacer to match the height of intake to the injectors.

Sort of blocked in all pictures, but here is one. All the holes are slotted to allow it to work in almost all cases. We have used about 200 of these rails without a single issue.

Thank You both. Was hoping one of those would work, decent price and came with -8 crossover tube.
