The Street HP™ uses the best features from Holley's race Bred 4150 HP™ carbs, but tamed for street and light competition use.
The contoured main body from the 4150 HP™ has a tumble polished shiny finish. 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 and drivability. A street HP base plate is used so there are plenty of vacuum ports for power brakes, PCV, etc.
