upgrading ?
i have a stock cube ls1 with all the bolt ons and heads and cam plus ewp, fast 90/90 and over the winter i plan on swapping out the f14 cam (232 234 .595 .598) for a more blower friendly cam, a set of 317's and a p1sc-1. the injectors i have on there now are 36 lbhr and i was planning on running between 8 to 10 psi. do i have enough injector to feed the motor.
its a stock bottom end motor and i will be up grading the rod bolts at the same time and i want this thing to make at least 550rwp +, do you guys have any suggestions on the cam?

Maybe Bob at EPP will chime in but I think at 80 percent duty cycle and at 550 rwhp you will need more than 42's and 60 or less so might as well install 60's.
60's seem to be the most common size to use in the over 500 and less than 600 rwhp range giving you some room to go down one pulley size, make some addtional HP and still have enough injector left.
You will need a fuel pump too. The stock pump won't handle the addtional volume unless you already have the Racetronix Kit.
