I have a normally aspirated 383 TPI engine with high flow heads, mid range cam, headers, custom prom, etc. It supposed to dyno near 450-500 hp at the flywheel. Would I have any problems with 30lbs injectors (that I already have) opposed to 24lbs injectors that would be just at thier limit at peak hp.

Supposedly I can reduce the injector pulse width to reduce the fuel to lean it out in case it would be too rich. My concern is lack of fuel with the 24's at peak hp.

What do you guys think? Anyone with a similar setup? I want to burn this prom but don't know whether I should get 24's or stick with my new set of 30's.
Thanks

 

Stick with the 30's. I am running them on my 350 and everything is great. Plus, they give you room to grow in the future.
