Default 42lbrs enough?

Will the green top SVO 42lbrs be enough injector to support a 402 stroker thats making 650-700 hp at the crank? itll have a 300 hit on it to make it a flat 1000hp at the crank but itll be a wet kit plate so I dont think itll be a problem.

Hey,big am not a expert,but i would say your injectors are maxed out!!Only because I am running stock ls1 w/a small, 67m turbo with green tops ''42'' and on the dyno the duty cycle was 90%!!! and i only put down 470wrhp...THE IS GOOD NEWS I HEARD THEY ARE UNDER RATED!!!

If you plan on doing a wet shot, they will be plenty.

I have a very healthy motor with the amount of flywheel power you mentioned and I have never seen my injectors much higher than 72% or so I believe.

With a big fuel system, and rails, they flow like a 49lb would. I run them, I'm sure your usuing a stand-alone fuel system for your nitrous anyways.
