The carbureted manifold has a 4150 flange to work with all mechanical secondary square bore carburetors. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features like better plenum and runner geometry for improved charge airflow. The isolated design of the air\/fuel passages helps to increase charge air density and performance.\n\nThe intake manifolds are designed for use with 289-347 cubic inch Small Block Ford engines with a 8.2\" deck height.\u003c\/div\u003e\u003ch3\u003eFeatures:\u003c\/h3\u003e\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eSingle plane design with isolated plenum for cooler charge air temperatures\u003c\/li\u003e\n\u003cli\u003e4150 square bore mounting flange\u003c\/li\u003e\n\u003cli\u003ePower band: 2500-7500 RPM\u003c\/li\u003e\n\u003cli\u003eHeight: front 5.58Ó, rear 6.40Ó\u003c\/li\u003e\n\u003cli\u003ePort size: 1.82Ó height, 1.04Ó width\u003c\/li\u003e\n\u003cli\u003eExtra material allows for porting to 2.00Ó height, 1.20Ó width\u003c\/li\u003e\n\u003cli\u003eAccessory ports under the carburetor in 1\/8 NPT, 1\/4 NPT and 3\/8 NPT sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\t\t\u003cdiv class=\"brandbox\"\u003e\n\t\t\t\u003cdiv class=\"brand-content\"\u003e\n\t\t\t\t\u003cp class=\"brand-title\"\u003eAbout Holley\u003c\/p\u003e\n\t\t\t\t\u003cdiv class=\"brand-main\"\u003e\n\t\t\t\t\t\u003cdiv class=\"brand-image-container\"\u003e\u003cimg class=\"brand-image\" width=\"387\" src=\"\/\/images.holley.com\/387x\/websitebrandimages_holley.jpg\"\u003e\u003c\/div\u003e\n\t\t\t\t\t\u003cp class=\"brand-text\"\u003eHolley Performance Brands is the undisputed leader in carburetors, fuel pumps, fuel injection, intake manifolds, fuel injection, and fuel systems.\u003c\/p\u003e\n\t\t\t\t\u003c\/div\u003e\n\t\t\t\u003c\/div\u003e\n\t\t\u003c\/div\u003e","brand":"HOLLEY","offers":[{"title":"Default Title","offer_id":62137829982579,"sku":"300-277","price":467.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/6289\/0099\/files\/8c6302a860ca8b4efd4977f5ec4d5cf6a34e8df0.jpg?v=1767392594","url":"https:\/\/dspperformancemotorsports.com\/products\/holley-single-plane-4150-carbureted-intake-manifold-300-277","provider":"DSP PERFORMANCE MOTORSPORTS","version":"1.0","type":"link"}
