What injectors for a 383

Hey guys;
Just curious as to what injectors ya'll are running with 383's. I need 30 lb injectors to go with my 383 9.5 compression 180cc AFR heads and a Hot cam on top of a HSR system. Thanks.

I have been running 24 # ford motorsports injectors in my 10.5:1 383. I will also be running the same injector in the new 406.

My motor is almost the same as yours, 383 - 30# injectors - 9.7:1 comp - 195cc trickflows - 214/220 cam - HSR manifold.

30 lb injectors is what I suggest.

With my 383, 190 AFR, HSR, 10.4:1, and a good cam I see around 80% Duty Cycle at 6000 rpm with an AFR of around 12.5.
So if I one day I make more HP I will have to upgrade to 36 lb.
