Willy's 500 CFM Alky Carb w/ ext adj block & Ext Bowls

SKU: WCD44121-XV

Like our basic 44120, this carb also has 1-3/8" venturi and 1-11/16" throttle plate. The unique feature this carb offers is our billet metering block with externally adjusting jets. This feature will give you more horsepower and the convenience of being able to make jet adjustments without disassembling the carb all in the click of the wrist.


The extended bowl option offers extra volume for the alky 2 barrel and is a must for the 500 cfm alcohol racer.

Please note:  All carburetors are built to order and dyno tuned before shipping. If time is a factor for you, please call to verify lead times. (618) 262-8021
