Holley 0-80556-2RD - Holley Ultra Dominator Carburetors

Ultra Dominators feature all aluminum construction which saves 3.8lbs off the top of your engine (Nearly 8lbs when used in a 2x4 setup!). The main body is tumble polished with a fully hand polished inlet/venturii area for smooth air entry and less turbulence. Carbs feature Teflon coated, slabbed throttle shafts with low profile button head screws and anodized aluminum throttle plates for improved air flow and corrosion protection. 12 hole billet booster inserts provide an improved fuel signal and superior fuel atomization.

Other features include billet metering blocks with adjustable emulsion, idle feed, and power valve channel restrictions for infinite tunability to each engine. Clear fuel level sight glasses in the polished aluminum fuel bowls make for easy, no mess float adjustments. Replacing the internal linkage is a fully adjustable external linkage that can be adjusted for 1:1, progressive, or soft progressive throttle activation.
