Injectors for a 383
I'm building a 383 for my IROC and for some reason I started thinking about injectors. I have 22# flowmatched injectors right now. Will those flow enough fuel for a 400 hp 383 with a SuperRam? I am making a custom chip for this setup if that matters.

The 22's can fuel a 383 but you might get above the ideal 80% duty cycle with them. I'm running GM 24's on my ZZ4 so I think you should/could run 30's.

as far as i've found 22lb injectors will run a mild 383, but they don't leave much room for modifications to them. 24 is enough for a strong 383. i'm going with 30 to leave room for possible supercharger later, but also just so i know i'll have enough and don't need a ton of fuel pressure to keep up.
