Top 10 750 Holley Carburetor Vacuum Secudays

The Street HP uses the best features from Holley’s race Bred 4150 HP carburetors, 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 and 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.

The Ultra Double Pumper Carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061-T6 billet aluminum. Three different anodized color options (Red, Blue or Black) allow for a personalized look while maintaining the ultra high strength and durability you get from billet. They weigh in at approximately 5 pounds less than a comparable zinc carburetor. The new Ultra Double Pumper Carburetors have an enhanced fuel curve for optimum performance, with many more features such as aluminum construction, anodized billet aluminum metering blocks and base plate, four corner idle for precise idle control, mechanical secondaries for great performance, clear fuel level sight plugs for easy, no mess fuel level adjustments, Ford automatic transmission kickdown for use on popular Ford transmissions, four vacuum ports for all necessary vacuum accessories and for the first time on a Double Pumper, factory pre-set electric choke for easy, fast cold start-ups. The clean, polished look coupled with Red, Blue or Black metering blocks and throttle body will certainly set your ride apart whether you are at the show or track.

Holley is proud to introduce the all new aluminum Track Warrior carburetors. They utilize the best features from Holley’s Race Bred Classic 4150 HP carbs, and we have added billet metering blocks, billet base plate, and knurled (hand adjustable) curb idle screws. The Track Warrior features an aluminum contoured main body design and has screw in air bleeds for precision tuning capabilities. The all new aluminum Track Warrior weighs up to 40% less and adds horsepower and torque, pushing on the track performance to the next level!!
