Is a 19lb Injector too small for a LT4 Hot Cam?
Thanks Scott

 

I'm using 24's

If you don't have an adjustable fuel pressure regulator, then yes, they are way too small. If you can bump up the fuel pressure then they may work. I've heard that TPIS has used them on engines up to 400 ci without problems. I'd say try them and find out before you rush out to get a set of #24s. A scan tool will tell you if the injectors are too small if you see it lean out on hard accelleration, or if your injector duty cycles are maxed.
