My carb is a something I pieced together from ~ 4 old carbs... it's a bit "Frankensteined" carb....The important parts are a 750 Proform main and an e85 conversion kit I got off ebay from Rob Mix. After a whole lot of tuning, it is the one that stays on my 408 because it is fast and consistent. I also have a new Holley 950XP carb that is ~ 0.5mph faster, but it is unreliable for a foot brake racer like me. It has an occasional hesitation at the hit of the throttle that has cost me a few races...now it sits on a shelf for when I switch to leaving off a button.
