Is the #120 jet actually the universal "Magic Number" for small blocks?
Been doing some testing on a few different engins lately and after messing with a few diffrent sizes, the #120 jet seems to be the absolute sweet spot for throttle response and top-end.
It cured the low-end bog I was getting with the stock setup. Are you finding the #120 is the baseline, or does altitude change the game that much for you guys?
