An FCR39 or an Eldebrock. I think most agree that the fcr is the most bang for the buck but also the biggest headache to get to fit. The brock is nice if you change elevations alot because of on the fly jetting. The brock is 37mm.

We have been trying to get an HS40 working over at central. IT would work well if it weren't for a blasted idle issue we are all having. Softening the throttle loosens the spring too much at idle and periodically you get high idle. Without a spring mod your damb thumb would fall off. The brock is also noted for having a semi stiff throttle compared to stock. The HS is almost free if you can find one
