Fuel rail help
Need to install new red , maybe Fast or some other, fuel rails, this is for looks only. Trying to dress up the motor. I already have valve covers, Just want to add fuel rails and coil relocation kits. I'd like to add the rails, fuel lines and what ever else I need to make it all look good? Some say I need to change the injectors to make this work out. Is that right? Please anybody that knows how to do this mod please chime in. Thanks

LS2 injectors are taller than LS3 and LS7, so if you change the intake and fuel rails, you need to raise the injector height to allow the rails to clear the intake.

Holly makes fuel rails that are a direct bolt on for LS3 with stock injectors. I put a set on with ProForm valve covers and their coil relocation kit. Made up my own fuel lines to connect fuel rails together and to factory hard line at fire wall.
