Hey guys. I have a mild 350 sbc in my street rod. Really do not know the specs on the motor. But it is no street demon for sure, just a simple cruiser. I installed a 750 double pumper on it, basically because it looks really cool. It came with #74 jets. Had a hesitation when feathering the pedal. so I dropped it down to a 66. Way better but still not enough. dropped it down again to a 64. Even better but again not enough. decided to use a 60 but the store was out of them and only had #56. Does anyone think that that would be too small? Not a big deal to change them out but I really do not have much time these days. Would like to be done with this issue.
