Which Injectors for a Performance LS

[ADiCarlo]

Thanks everyone for the input. I'm probably going to go with 60lbs injectors as the motor makes 510 right now so i'm approaching the top of the range for the factory set up.

Anyone recommend a specific brand for LS3?

You are fine with the stock 42 lb injectors at 510 hp. I'm running a 60 in my 760 hp engine. I can't stress enough how much trouble your going to have trying to tune with injectors that are way to large for the application. The injector is at it's worst at on and off, it will drool when it starts and stops, with an injector that is too large the on cycle ends up being very short and the off time being long.
