COMP Cams 12-600-4 Details

Have you ever been to the races and heard how nasty the cams sound? COMP Cams has developed the Thumpr series of cams that give you every day drivability, but have that nasty race engine sound. Pick the cam that fits your application, add a set of COMP Cams hydraulic lifters and you will be the talk of the town.

High performance street, stock converter ok, best with 2000+ converter and gears. Choppy/thumping idle.

If you want a true hot rod sound without dumping a bunch of time and money into valve train upgrades, gears, and stall converters, this is your cam. Awesome hot rod idle and performance. I love it and would run one in any of my builds.

Will this cam work ok with a stock Goodwrench 350 (edelbrock EPS/Holley 670) and 700r4 in my 1957 Chevrolet Bel Air? What size stall converter would you recommend, I was thinking a 2200 stall? I have a 3.23 ratio diff, and 205/70-14 BFGoodrich radials.
