I'm in the final stages of restoring "Big Sweety" a 1971 Chevelle SS with a 350SB, 350THM, 350/350HP cam, small rise, stock appearance intake from GM Performance (as is the cam) I currantly have the stock Rochester carb installed, however the original owner had removed the choke linkage, secondary butterflies as well as some other parts. I want to stick with a Rochester Q-Jet. Are there any suggestions on what CFM to go with and where would be a good place to obtain a well rebuilt unit?
