Holley Street HP 750 CFM Carburettor 4150

• Genuine Holley Race-bred HP performance, street-tuned - Built from Holley. 4150 HP features with street/strip calibration for sharp throttle response and drivability.
• Precision tuning built in - Screw-in air bleeds and four-corner idle give you finer control over mixture and idle quality.
• Hard launch fuel control - Mechanical secondaries, dual accelerator pumps, and dual-feed inlets support strong acceleration and consistent fuel delivery.

The Holley Street HP takes the best features from Holley’s race-bred 4150 HP carbs and blends them with the practicality needed for street and light competition use. It features the contoured 4150 HP-style main body with a tumble/vibratory polished finish, plus screw-in air bleeds for precise tuning. 

On applicable models, the Street HP base plate provides extra vacuum ports for common street accessories such as power brakes and PCV. With mechanical secondaries and dual accelerator pumps, it also brings the punch and feel enthusiasts want from a true street/strip carburettor.
