Fuel a lq4
Building an lq4 408
Callies 4" crank
K1 H-beam rods 6.125
Wiseco pistons 4.030 2cc valve reliefs
243 heads with minor port job
ls3 intake
very tame cam.
Looking to make around 500 hp and need to know what upgrades to fuel system other than injectors to feed the motor.

I would upgrade that pump to a Walbro 255lph, did mine back when I was having some problems out of the stocker, very easy install. Just watch the float when it comes out not to break it, unless you want to replace anyway in case you are having some issues running empty before the gauge shows E. I might also think about going L92's instead of the 243's unless you already bought them, besides the LS3 intake only works with rectangle ports such as the L92's. Strokers/compression really make them useful. That also might be an issue if you've already bought the pistons, make sure the reliefs will work with the big L92 intake valve.
Look forward to getting that flag man.
