Any one running 383 with stock injectors
I was told 22lb injectors will only support 280 HP. Seems low to me. Are any of you running stock injectors with a 383? If not what are you running and did you change fuel pumps?? Thanks

I ran the stock 22's with the stock tpi intake, 383, afr heads, etc. Ran fine even with the stock chip and a mild cam.
Once I changed to the superram intake and 30lb injectors, I had to add an inline fuel pump to keep up with the fuel flow.

I'm running the stock 22# with my 304rwhp which may be close to 340 crank hp on my car. On a 383 I would upgrade them for sure to be safe but you may run them for a while. Just make sure it doesn't get lean or you can damage something.
