i would do 550's or even a step bigger. it's safer to run at 75 percent cycle with room to grow than to push the limits of a smaller injector that can handle the job at say 90% , also why a stage 6 clutch? if this is to be a DD, you will hate your life. a sprung stage 2 would suite you finely. i've seen oem replacements handle upto around 300 safely, just my .02

I think there's a chart or a calculator on RC's website that will tell you exactly size injector to get for your particular setup. There's a formula for determining it, don't leave it to a guess.

^^+1^ good advice , guessing ain't an option unless you plan on wastin your money or possibly destroying your motor. Choose accordingly

:roll:550 will be to small way to small for 450whp. 880 or 1000 is what i would recomend you migh be able to get away with some 760s or so but they would be pretty maxed. and stage 6 clutch ehh you'll get use to it but on the down side i dont think your blox ami will flow enough for 450 nor the LS head but good luck

I agree. They do need to be bigger than a 550

Yea, call RC and talk to them, they'll tell you exactly which injectors to run.

i run 1000cc injectors. you can be too small, but not really too big. get some injectors with some room to go in case you get bored with your power level and want to up the boost some more.
