Get ready to experience tire-smoking performance without breaking the bank! The all-new Aluminum Street HP carburetor is designed to be up to 40% lighter, making it a budget-friendly choice for enthusiasts.

Holley is thrilled to present the latest in carburetor technology: the Aluminum Street HP™. This model takes the best features from Holley's race-proven 4150 HP™ carbs and adapts them for street and light competition use. With its aluminum contoured main body design inspired by the race-winning 4150 HP™, this carburetor boasts a polished finish and screw-in air bleeds to allow for precise tuning.

The metering system is equipped with a timed spark port for a vacuum advance distributor, perfectly calibrated for hot street and strip setups. This ensures exceptional throttle response, drivability, and top-notch performance. The Street HP base plate provides ample vacuum ports for power brakes, PCV, and more.

The Aluminum Street HP combines the finest elements of race-bred HP and Double Pumper designs, creating the ultimate carburetor for both street and strip applications.
