That's one thing for sure about Rochester Quadrajet carbs. You either hate them or love them. I am one that actually loves em. The one I had was getting worn out at the throttle shafts and constantly leaked gas. So after a long internal debate, I sprung for a new Stage two carb from Jet Performance. Totally sweet. I have a rebuilt 600 cfm Edelbrock on the shelf that I was gonna use, but it's gonna find a home elsewhere. I thought about a Holley spreadbore, but didn't hear much good about them, so I stuck with what I was familiar with. No regrets.
