My experience is a one barrel carb gets miserable MPG. That was in a '70 Nova with a factory GM Monojet on a 230 I6. Great little carb., just not great mileage.

I got better mileage with a 1977 305 with a factory 2 barrel.

Inspired to be different. Different in a way of my own, not in a way that others strive.
