Quote: What size carb do you have now? If pro systems build a carb it mostly likely would be a 1100
1050 Quickfuel Dominator, same one my dad ran on his 540 8 years ago.
I know this has nothing to do with accelerating a car, but we dynoed a 1.590 x 1.750 4150 on a 420 with a 2in spacer. Then we sent the 420 to Gabby who opened it up to dominator flange and we tried a 110mm blade SV-1 w/spacer.
We saw a 33hp increase. Obviously this huge increase was over a large 4150 and not a purpose built dominator.
