    292 inlines like a lot of fuel, I drag race one and run two afb four barrel carbs. If I were to put one on the street I would run two Rochester 2gcs. Mileage sucks but with carbs equal distance from the intake ports you get more efficient fuel distribution. If you wanted economy, you wouldn't have a 292

    Really don't want to have to screw with multiple carbs anymore.

    I'm running a Holley 390. Fresh off the dyno, made 285hp but motor man said it ran out of carb. He suggested a 600cfm. but I have heard 390 is better for the street.
