{"product_id":"4150-double-pumper-600-cfm-carburetor","title":"4150 Double Pumper 600 CFM Carburetor","description":"The Holley Double Pumper Carburetor, Model 4150, is a 4-barrel, 600 CFM unit with a square bore flange, designed for enhanced performance and responsiveness. It features mechanical secondaries for powerful acceleration and dual accelerator pumps to deliver additional fuel precisely when needed under initial throttle input. The manual choke allows for fine-tuned cold start control, while dual feed fuel inlets ensure a constant, high-volume supply of fuel.\n\nThis carburetor is optimized with a street\/strip calibration for immediate out-of-the-box performance and has been 100% wet-flow tested by Holley technicians. It is engineered to replace common carburetor styles including Holley, Edelbrock, Carter AFB, and Autolite, provided they have the 5 3\/16\" x 5 5\/8\" square bore bolt pattern. Users with spreadbore intake manifolds will require an adapter for installation.\n\nThe design of this Holley carburetor is specifically intended for lightweight vehicles. It is recommended for use with manual transmissions or with automatic transmissions that are equipped with a high stall converter and low rear-end gearing. The product includes an Installation and Tuning DVD to assist with setup. This carburetor is not legal for sale or use in California.","brand":"Holley","offers":[{"title":"Default Title","offer_id":52688679567672,"sku":"HLY0-4776S","price":628.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664205648.webp?v=1784892738","url":"https:\/\/store.motormia.co\/products\/4150-double-pumper-600-cfm-carburetor","provider":"MOTORMIA","version":"1.0","type":"link"}
