The Holley is a good carb, I'm sure, but not for the street. There is no better design than the spreadbore. There are more than just one that can tune a Q-Jet. Myself, Cliff Ruggles, Mat Klemp, the guy deerhunter suggested. You have to avoid the volume producers. There is no way you can produce one carb for EVERY combination on the road. Yes they say they need your engine and cam specs, but how can they build a "custom" carb in a week if they have hundreds of orders before yours? It can't be done. That's why Cliff is 6 months behind, at least. The hardest part of a Q-Jet is figuring out the appropriate settings, not the actual labor. Once you know what to make each setting, 90% of the work is finished. Like I said, my Q-Jet is tuned so well it runs like FI. Just like it was intended when the engineers 1st designed it. I can pump my carb once on a 20* morning and she fires right up. In fact, if the carb is tuned properly to your engine, you don't even need a choke. I can start my car without setting the choke. I set it for insurance.
