Fueling & Injection - Fuel Injector Question

Im building a LS1 with trick flow heads 215cc 2.040/1.575 valves, 238/242 duration and 595 595 lift, 92mm Fast Intake, 90mm TB, MSD coil packs, SLP long tubes, Jet Mass Airflow, SLP cold air....My question is what size fuel injectors should I use or can I use my stock ones???

i would recommend getting 37# or 42# injectors. that way you will have breathing room later for more mods.

you will want to get a tune for all of that plus these injectors BEFORE you run the car with these injectors
