The Street HP boasts an aluminum contoured main body design derived from the race-winning 4150 HP™, featuring a tumble-polished shiny finish and screw-in air bleeds for precise tuning. The metering system includes a timed spark port for a vacuum advance distributor, perfectly calibrated for a hot street or strip engine setup, ensuring you enjoy exceptional throttle response and drivability.

With a base plate designed for the street HP, you'll find plenty of vacuum ports for power brakes, PCV, and more. This carburetor combines all the standout features of the race-bred HP and the Double Pumper, creating the ultimate street/strip carburetor experience.
