Not Ranked
My carbs are a new out of the box set of 4160 , 600cfm Holley carbs, manual choke , vaccum secondary. I'm told this carb has a size 66 front jet and a metering plate equal to a size 64 jet. The linkage is a Branda unit that turns around the carbs (putting the choke on the drivers side).I'm not sure of the squirter size but they are stock units.
My Dyno guy said that my motor is not running at 2000rpm off the jets. He seems to know what he is talking about but its a little over my head. I know the idle circuits are predrilled and I thought that as soon as the throttle is applied the jets are used . He said that there is a spot between these two circuits that my motor is in before WOT . Apperantly when I'm cruising (normal around town driving) my car is in this intermediate circuit. The Dyno guy said some larger carbs actually have a provision for this but mine doesnt. I hope I did a OK job describing my delemia
