I am planning on making 400-425rwhp N/A with a high compression 347 setup.

I have stock rails right now, with 36lb injectors, 255lph Walbro fuel pump, and Aeromotive FRP.

I dont WANT to have to spend $400+ on rails and fittings, but I will if I have to.

Either way I will be getting new lines to replace the rubber stuff in the engine bay.

I make 490rwhp/630rwtq with my stock fuel rails. They'll work fine. I was going to do a dual feed on my stock fuel rails, but realized it was unnecessary.
