Carb size ???? 383 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Venturi size: As pieceparts noted, a venturi that\'s too big just won\'t give you the throttle response you expect. In other carbs like Webers, you can change the venturi size...in Holleys and BGs, venturi size is based on CFM although you can adjust to some extent.
Secondary type: Vac secondaries for sure unless you\'re going drag racing <img src="http://67-72chevytrucks.com/vboard/images/smilies/smile.gif" border="0" alt="" title="Smilie" class="inlineimg" />
