HolleyDAYS are here again! SAVE up to 20% on this part and hundreds of other Holley brands during the 2018 HolleyDAYS sale 11/15/18-12/31/18.

The Gen 3 Ultra Dominator features a brand new mainbody, brand new stateoftheart calibrations, high volume fuel bowls and sizes up to 1475 CFM! The patent pending GEN 3 mainbody is 5/16 taller than the previous generation! This new height allowed for larger radius air entries which were optimized using Computational Fluid Dynamics (CFD) software to deliver smoother flow into new fully machined, big bore venturii. The main-body also features an integrated idle bypass valve that allows for idle adjustments while maintaining the correct throttle plate to transfer slot relationship as well as an extended air cleaner flange for easy air scoop attachment when using the available air scoop adapter. Each calibration has been dyno and track tested to deliver proven performance!

  • All aluminum construction saves 3.8lbs. over original models (28% weight savings)
  • Hard Core Gray with black anodized billet aluminum metering block and booster inserts
  • Designed for use on Drag race, Pro Street, or any high horsepower engines
  • Calibrations optimized for today's larger race engines and new fuels
  • Fully machined from venturii throat to throttle bore for predictable & repeatable performance
  • Integrated idle bypass valve allows for adjustment of idle while maintaining correct throttle plate to transfer slot relationship
  • 12 hole billet booster inserts for superior atomization and crisp throttle response
  • Dual 50cc accelerator pumps provide the perfect amount of fuel from idle to full throttle
  • Fuel bowls provide 20% more fuel capacity while controlling slosh with internal baffling
  • Clear sight windows on both sides of bowls for easy and safe fuel level adjustments
  • Built in drain plug in front center of bowl provides easy access to empty contents of bowl
  • -8 (o-ringed) inlet threads offer a large variety of plumbing options and can be plumbed from either side
  • Factory ready TPS mounting points for use with data acquisition systems (Holley TPS P/N 534-214 available)
  • Knurled (hand adjustable) primary and secondary curb idle screws allow for easy idle adjustment without the use of tools
  • Contoured hex head squirter screws for streamlined airflow
