Well I've learned years ago, example, I picked up a 500cfm 2 bbl, put it on a 289 ford, awful gas hog, I started going done on the main jets, to try to get better mileage, finally I had a wicked flat spot, i was getting plenty of air but not enough gas, finally figured out you can only go 2-3 jet sizes smaller than what is in a certain cfm carb.
