On this episode of Engine Masters presented by AMSOIL, we take the mystery out of carburetor selection. More air means more power, but is there such a thing as too big? And how do you know when you’ve passed good? David Freiburger, Steve Dulcich, Steve Brulé from Westech Performance, and the dyno get together to compare carbs from 650 to 950 cfm on Our Ultimate Average 383 to help you find all the power and all the driveability.
