Injector Sizing Question

I'm trying to gain some knowledge on injector sizing. Does anyone know or know where I can find:
Maximum HP attainable with a 30 LB injector at 50 PSI? I'm also interested in the 26 LB and 36 LB figures at same FP. I'm sure my 26's are going stoich on my new motor and I'm trying to match injectors with my new combo.

TIA

355 CI, 11-1 CR, Mini Ram Intake, 58 mm TB, Canfield 200cc Alum. Heads, Hooker LT's, Comp Solid Roller .600 lift 242/248 duration @ 50 thousandths. The motor is begging for more fuel at WOT with the 26 LB injectors. I'm guessing the crank HP should be 510-525 with proper fuel and tuning. BTW, Engine Management by DFI.

Almost forgot........I'll be running a 150 shot occassionally. Probably the additional fuel through the injectors, a nice option on the DFI.

well if you were running just motor, 36#ers should do it, but your gonna eventually run nitrous so i would go bigger. like a 42# or so. It doesn't matter if the injectors are bigger than what you need just as long as the computer is tuned for it. Its better to have too much than too little of injectors and lean it out...

sounds like you have a pretty impressive motor there...sounds sweet!

somebody else might chime in here with a similar setup to yours and you can see what they are running, just be patience...
