Tough call. However, I think you should send yours out to pro systems, nickerson, or chuck nuytten, and get them redone if they are beyond a renew kit. Your carbs should be enough to support what you have i.m.o.

If yours are flowed up to 920fm, then that is plenty. Dominators would be too big and are not needed until you get to 540ci or so. You would lose throttle response with too big of carbs.

I have heard that the 500 came with 800cfm carbs. However, it has a 1-11/16th butterfly base plate. That tells me it is has a 750 CFM. All the 800's that ive worked with had a 1-3/4" butterfly. Now another factor is the venturii diameter and horn angle. All of which plays into the cfm rating.

How did you go from stock to 920 cfm?
