working on tuning 38#ers with cam, looks like i picked the right ones well i was planning on getting injectors that could flow enough fuel for about 540-550 FLYWHEEL hp, i picked 38# (37.8) racetronix injectors, they flow 43.65# at 58 psi. right now im at 12.1 ms pulse width at 5500 rpms in 3rd, ive got 6800 rpm rev limit. i am guessing the set up i have now is good for 430-440 rwhp:
f13 cam, specs in sig
afr heads
all the bolt ons, ls6 intake though
im sitting right around 60% duty cycle and im a tad on the lean side. this shoudl give enough room to get 90mm intake set up, mill the heads, and push up near 470-480 rwhp and have enough fuel. i know guys ask about what injectors to support what power levels so here are my results, hope this helps some of you out.

That's good to know. I was at 430whp on my stock 28's before added a FAST 90/90 setup that is pushing my duty cycle to 109% or 19.4ms at 6500 rpms. I just purchased a set of Bosch/Delphi 38lbsrs so that's good to know. I still need to add my custom ground Ed Curtis cam and 100shot dry.
