CHRY UPGRADE SERIES CARB

PROFORM's new 100% Aluminum Street Series Upgrade Carburetor is hand assembled in the U.S. Based on the wildly successful Billet Aluminum Street Series carburetors, these Upgrade Series street carburetors are constructed of lightweight aluminum, including changeable idle air bleeds for easy non-permanent calibration changes if needed. Fine-tuning is accomplished by simply changing air bleeds, not opening calibration restrictions with a drill bit. Each street carburetor features a metering block with a street performance calibration that is ready to roll right out of the box and developed for today's high-performance engines.
