Holley 0-1850S Carburetor

The Street uses the features from Holley’s race Bred 4150 carbs, but tamed for street and light competition use. The contoured main body from the 4150 has a tumble polished shiny finish. The metering system includes a timed spark port for a vacuum advance distributor and is calibrated for a street and strip engine setup for outstanding throttle response and drivability. A street base plate is used so there are plenty of vacuum ports for power brakes, PCV, etc.
