The carburetor-mounting pad is designed to accept all stock or aftermarket square-bore carburetors with manual or electric chokes. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features; like an updated plenum divider area, a 1\" shorter height than the 300-25 manifold, and a choice of two distributor clamp locations. The isolated design of the air\/fuel passages helps to increase charge air density and performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSingle Plane with Isolated Plenum\u003c\/li\u003e\n\u003cli\u003eSquare Bore Carburetor Mounting Flange\u003c\/li\u003e\n\u003cli\u003eIsolated Water cross-over\u003c\/li\u003e\n\u003cli\u003ePower band: 2500-7500 RPM\u003c\/li\u003e\n\u003cli\u003eHeight: Front 4.18\", Rear 5.28\"\u003c\/li\u003e\n\u003cli\u003ePort Size: 1.92\" height 1.20\" width\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIntake Manifold 1957-1986 262ci-400ci, 1987-later with Aluminum Heads\u003c\/p\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":52258605334840,"sku":"H00E 300-261","price":441.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-518741-3343438-square.webp?v=1778131308","url":"https:\/\/store.motormia.co\/products\/sbc-single-plane-intake-manifold-w-4150-flange","provider":"MOTORMIA","version":"1.0","type":"link"}
