Swerve,
I have done back to back comparisions between new Q-Jets and new Holleys and always find the Holleys hold the A/F ratio better than the Q-Jets.
My mileage and power went up with my new Holley too and this would indicate a better carb in the Holley.
The Holley is MUCH cheaper not to mention.
The Q-Jet is a good carb (when new) if you consider Chevy put it on both small blocks and big blocks with little to no changes in the carb but it just doesn't hold a candle to my 650 and 670 Holley according to my A/F guage, mph, and power.
Have you installed each on the same engine and installed a A/F guage to check them?
Most people don't like the Jet because they don't know how to tune it..........I have been tuning carbs for 30 years so that is not the case.
Clueless?
I don't know about that.
