I've never seen so many people agree on the q-jet. Most write them off as junk, and for good reason. The pot metal casting is junk. Another major flaw is the throttle shaft, which wears the housing and causes leaks around the shaft, requiring bushing the shaft hole. However, when you get a good one that will stay tuned, they're a good, economical carb. They do kill your torque curve when the secondaries open at wide open throttle. But for everyday driving, they're tough to beat. I only wish I could afford the Edelbrock Q-jet, it looks like a winner.
