How do those Class racers make so much power with those "inferior" Carter and Rochester carbs? What ever works for you is fine with me. I have about 100 carbs, no Holleys. I dislike Holleys, but I'm not stupid enough to take a sledge hammer to one, I'd sell it to some one who can, or thinks he can make it run. I ran a Holley for years, then woke up and started trying other carbs that ran just as good or better. I also have not bought a new carb in 30+ years. My friends that still race do run Holley carbs, but on their street cars run Edelbrock or TQ.
