1967' Eightbarrel, What speaks volume is that NASCAR paid Willy one and half million dollars for one days worth of work, because he got 1 1/2 h.p in that time frame, (and by the way Tony Stewart was there when that happended), and NASCAR called him because of his reputation. You know of any other carb. builder who got paid that, I don't think so. His carburetors he makes (patented), 650 CFM will work on a 950h.p. With his carbs. you can tune every cylinder perfectly, and no flood stall with his patented bowls (Holley has been trying to buy him out for years). Just two years ago, every racing engine builder engine was 1-2 h.p apart, and Willy came in with his new carb., and got 20-30 h.p on the first day. Like I said he beyond genius, and a really nice guy to boot. Before you doubt someone, you ought to know your facts, my carb. does in fact make another 30h.p., every carb. he does goes on one of dyno's ( he has three), before it leaves his shop, so he knows exactly what h.p. it makes. Another nice thing that he does, is he will set them up for ethanol, if you are running that. Ask any racer and he will tell you if you are not running a Willy's carb., you are simply are not competitive.
