Holley 0-82951 950 CFM Street HP Carburettor - 4150 Mechanical Secondary, Square Bore, Polished

Brand new Holley Street HP 950 CFM four-barrel carburettor, list number 82951-2.

The Street HP takes the contoured main body and screw-in air bleeds from Holley's race-bred 4150 HP series and calibrates them for hot street and strip use. It sits right between a race HP and a Double Pumper — the tuning ability of the race carb, with the drivability and vacuum ports you actually need on the street.

Suits

Hot street and street/strip V8 builds up to roughly 700hp — 350 and 383 Chev, big blocks, and carburetted LS builds running a square-bore 4150 intake. Best suited to lighter cars with a manual, or an automatic with a high stall converter and low gearing. On a heavy street car with standard gearing you'd be better off on a 750.

Condition

Brand new, unused. Sold as pictured.

Please Note

Holley has discontinued the 0-82951 — the current replacement is the aluminium 0-82951SA. If you want this exact list number, they are only getting harder to find.

This is a performance carburettor intended for race, off-road or pre-1966 vehicle use. A 950 CFM carb needs to be tuned to your combination — buy it expecting to jet and tune it, not to bolt it on and walk away.
