We’re willing to bet four tires and fuel for your IMCA style Modified that if you look in any rulebook in the country you’ll find at least one reference to Holley’s legendary 4412 two barrel carburetor. By far and away this is the carb of choice for sanctions and tracks running two barrel motors. And that doesn’t matter if it is a mini-stock from Florida, a dirt Modified from Missouri or a Super Late Model from Wisconsin (yes some of those do actually use 2 barrels).

There is no doubt that Holley carbs have powered more racers than all others combined. But the Bowling Green based company has just changed the game again. Recently, Holley proudly introduced their all new Ultra HP 2 Barrel. Holley 2 barrels have been a mainstay in oval track racing for decades, but racers always want more. They want more tuning ability, more durability, more weight savings and more features, so Holley listened and designed the all new Ultra HP 2bbl.

It delivers the proven results of the Ultra HP 4bbl but now in a 500 CFM 2bbl. It’s all aluminum so it provides nearly 50% weight savings. It has no choke tower and an all new air entry area for smoother air flow, yet it retains the critical venturii and throttle bore dimensions for rule racing. It has large capacity HP fuel bowls, wedged float, dedicated race-only throttle lever, billet metering blocks & base plates, plus much more. The new Ultra HP 2bbl carbs are available in two finishes – a vibratory polished with black billet (part number 0-4412BK) and a Hard Core™ Gray hard coat anodized with black billet (part number 0-4412HB). They are already approved for use in the NASCAR Mid-West/West Coast Late Model Divisions and Holley expects more sanctioning bodies to approve them soon. Check it out at www.holley.com and look in the pages of Circle Track for this carb to appear on a motor build in the very near future.
