Holley HP Crate Racing 650 CFM 4 Barrel Carburetor

Description

4150 HP CARBURETORS

Holley Pro-Series HP Carburetors set the standards by which all competition carbs are judged. Built only for all-out performance, Pro-Series 4150 Carburetors have mechanical secondaries and perform like the more expensive “modified” carburetors at a considerably lower cost. Air horn and choketowers have been removed to improve air flow, venture sections have been modified, and the through-holes have been machined to .440″. Pro-Series carbs have been fitted with 4500 Dominator fuel bowls, high flow power valves, accelerator pumps equipped with severe usage diaphragms and have improved main metering circuitry
