Tire smoking performance has never been so affordable! The all new Aluminum Street HPs weigh up to 40% less and are even easier on your wallet.

Holley is proud to introduce the all new Aluminum Street HP™. They utilize the best features from Holley's Race Bred 4150 HP™ carbs, but are tamed for street and light competition use. The Street HP features an aluminum contoured main body design taken from the race winning 4150 HP™ and has a tumble polished shiny finish and screw in air bleeds for precision tuning capabilities. The metering system includes a timed spark port for a vacuum advance distributor and is calibrated for a hot street/strip engine setup for outstanding throttle response, drivability and maximum performance. A street HP base plate is used so there are plenty of vacuum ports for power brakes, PCV, etc.
The Aluminum Street HP takes all the great features from the race bred HP and the Double Pumper and combines them into the perfect street/strip carburetor.

  • Aluminum construction for weight savings and long lasting good looks

  • Contoured venturi inlet offers balanced airflow for increased horsepower
  • Screw in air bleeds for precision tuning capabilities
