I think the biggest downside of the Q-jet is that it has not been made for a long time and there are fewer and fewer people that will spend the time with them, therefore the expertise is going away. They can be made to run very well, and some Holley's can be a pain in the a$$ to get set up right. I also know that from experience. Both carbs have their place, and I think it is very narrow minded to say there is only one answer. I do happen to have a Holley on my racecar. I also have been racing 37 years. In different circumstances I would not hesitate to run a Q-Jet. I also still run the more antiquated tri-power. With no other changes, it ran 0.15 seconds better that the best I could get out of my old 750 Holley, and that was comparing the first time out for the 3x2s to a fully prepped Holley. Again, each setup has its advantages and disadvantages, but you cannot say that any of them is all bad or all good. It is true that you have more choices on flow capacity with the Holley. But maybe everyone doesnt
Need that flexibility.
