At what point would anyone upgrade the size of thier injectors. I have 19 pound on my 305 with a ton of mods which include a cam.
I will be upgrading the heads and intake this month. The car runs great. I just wanted to know at what point did some of you where forced to upgrade your injecters. Because I get conlfictng storys. Some people I talk to say your a fine with 19 pound untill your break the 370 hp range other say I should be running bigger injectors already. I am making somewhere in the range of 300 hp 1/4 time 13.9 at 99 mph. (305 tpi 5speed) Please give me details and sights where I can go.

Thanks,

 

I'd say when you begin to run lean...monitor the O2 sensor voltage and keep an eye on the plugs.
