here's what i got, 2004 GTO,
trickflow LS1 engine kit, H/C


FAST 102mm intake manifold and throttle body
FAST Fuel rails

uninstalled right now, it should put out 515-525 hp when on,

does anyone know if 36lbs injectors will be enough? also do i need to buy a new fuel pump or is the stock one good enough?

I would rec. replacing the fuel pump and inj. for that power range. 36# should be plenty for the power now but 42# will give you room to grow if you add any more down the road. Give me a call if you have any questions I will help you get what you need.
