Why run dual quads?
Good info and lots to drool over, thanks to all! I'm not smart enough to tune any carb much less multiples, but it's fun to think about.
I put a dual quad on my car when it had a '73 340 (low comp smog motor) in it. Used two out-of-the-box Carters, 650 AVSs IIRC. Progressive linkage. From sea-level to 4000' el. never had a problem starting or running. Got over 20mpg on the highway. Drove it cross country at least once.
Had no problem with no thing about it. Throttle response was perfect...no bogs, lags, stumbles or any other issue.
That was with a manual trans and 3.23 rear gears.
DID get waxed by a Boss Mustang once. That was at 4000' el. with a trunk full of car parts (I mean full...including the OEM intake manifold), and two passengers...each of them 6'+ big guys. If you have to ask why, you were evidently never young and stoopid.
OR, maybe I was just stoopider. There is a very high chance of a pegging the truth-o-meter on that possibility.
Have a sibling that drove it some. She said NO one came close to HER racing in town. I don't know about that, but she swears it was so. No, I had no idea she was pulling them kind'a stunts with MY car. Trunk probably empty...and her AND her buddy wouldn't have weighed much more than just me...if even as much.
