Holley Aluminum Ultra XP Carburetors
Holley's Ultra XP carburetors are up to 38 percent lighter than their traditional carbs, offer 20 percent greater fuel capacity, and include a host of other features. One of the main perks is an integrated idle bypass valve that allows for idle adjustments while maintaining the proper throttle-plate-to-transfer-slot relationship. You'll also get all-aluminum construction, fully tunable billet metering blocks, billet base plate, adjustable secondary linkage, and knurled (hand-adjustable) curb idle screws. Enjoy the ultimate in square-bore race carbs; order the Ultra XP carburetor with options best suited for your race application!
Some of the many other features include:
* Your choice of several finishes and CFM ratings (from 600 to 950)
* Contoured Venturi inlet offers balanced airflow for increased hp
* Dual accelerator pumps provide the perfect amount of fuel, from idle to full-throttle
* Clear sight windows on both sides of bowls for safe and easy fuel level adjustments
* -8 AN (O-ringed) inlet threads offer a large variety of plumbing options from either side
* Mechanical secondaries for perfect off-the-line launches
* 100-percent wet-flow tested by Holley technicians
