Just curious what some of you have used for carb size on say 500-540 BBC's on the spray? I have a 1050 pn8896 dominator that Patrick worked over last winter for me and have been wondering if I should move up to a bit bigger carb. This one seems to be working pretty good, just wondering if a 1150 or bigger would be worth anything? Turning the motor 7500 - 7700 at the shift points. Is there anyway to tell short of just trying one?
