Holley 4150 Aluminum Street HP Carburetors

Holley aluminum Street HP carburetors make tire-smoking performance affordable! They utilize the best features from Holley's Race Bred models but are tamed for street and light competition use, weighing up to 40 percent less and are even easier on your wallet. Each Street HP carburetor features an aluminum contoured main body design with 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 is plenty of vacuum ports for power brakes, PCV, etc. Show Less
