I wuz thinkn' the SS series 750 
Why? Do you drive it to work all year?
Mine is the 750dp race with Annular boosters and adjustable air bleeds, adjustable emulsion bleeds and billet metering blocks.....Tight convertor = annular boosters for best performance with a big carb.
Runs better than any carb I have ever had and mines a driver. Best carb out there for the money. Put an eddy on it you want to, I pulled the carter 625cfm off this engine, and its a nice running carb, but it really doesn't perform as well when you step on it. With all the tricks I could do to it, it still had a lean spot on hard accel.
