I have a l24 bored 10 over with flat top pistons and a medium'ish cam. I want to run pretty high compression and was wondering as far as carbs go if I be better off with single 4 barrel carb (Bob Sharp setup) to get the best cfm or my 2 single updraft carbs. I can't afford the triple Webber's for 1500 dollars and I am wondering for the best bang for my buck what I am best off doing. I get mixed answers and opinions in my research. Also I plan on putting my Snow Performance water/meth system on it so I can run pump fuel if that makes any difference.

SUs will flow that no problem, if you can dial them in right.

I would use the SU's . You can modify them to make damn good hp.
