What size fuel injectors???? HELP ME!!!

[RyanU1]

I have a 93 z28 automatic that i just rebuilt. I had the motor bored and stroked to a 383. I used a forged crack, 6" H-beam rods and and forged dish pistons. My heads have been CNC ported and Bowl blended. They contain a 2.00"/1.55" valves with aluminum 1:5 race rockers. My cam is a comp cam 220 ink 230 ext with .510 of lift both ways. I have in stalled a BBK twin 58 mm throttle body and am ABOUT to purchase an LT4 intake and have it port matched to the throttle body and add an adjustable fuel pressure regulator. I just dont know what size injectors i should go with. My car dynoed 320 to the rear wheels but that is before me adding a port matched intake and adj fuel prssure reg and injectors. So if anyone could help me figure out what size injectors i will need in the end i would greatly appreciate it.

Thanks
Ryan
