The 3.75-tall cast aluminum main body fits all 4150 and 4500 carb flange manifolds without requiring an adapter plate. A street throttle arm, Moly-coated throttle shafts and built-in provisions for a standard GM three-wire TPS mount add features to this carburetor that are ideal for any user. Multiple vacuum hook-ups keep this carburetor usable on the street but still ready for the track with larger capacity fuel bowls and four circuit billet metering blocks with screw-in emulsion bleeds. All of these features make for easy tuning and great versatility in many applications. The 20% larger capacity fuel bowls feature internal ribs to control fuel slosh, and a sculpted baffle directs incoming fuel to the sides to minimize bubbles. The floats have corner cuts to avoid shutting off the fuel flow during hard cornering, and jet extender notches and jet extenders in the rear to keep the jets covered in fuel under hard acceleration. VRS carburetors allow users to externally adjust idle bypass air and the adjustment screws are accessible without removing the air cleaner\/scoop. The advanced idle circuit features interchangeable idle discharge jets in all four corners to allow for a smooth, clean idle with the use of big, low-vacuum camshafts. Normally found only in high end racing carbs, the VRS includes fully adjustable intermediate fuel circuits, which help to provide incredible throttle response. Finally, for greater control at high RPM, the high speed\/main fuel circuit is split into two bleed circuits ¨C one each for the lower and upper sections. As an additional feature, the power valves are located on both primaries and secondaries to support optimized jetting. The power valve will add fuel as necessary while the power valve protection circuit prevents diaphragm damage from backfires.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifics and Features:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003eAccel Pump Well Size: 30 CC\u003c\/li\u003e\n\u003cli\u003eBarrel Quantity: 4 Barrel\u003c\/li\u003e\n\u003cli\u003eBody Height: 3.75 IN\u003c\/li\u003e\n\u003cli\u003eBooster Type: Standard straight leg\u003c\/li\u003e\n\u003cli\u003eBore Diameter: 1.6875 IN\u003c\/li\u003e\n\u003cli\u003eChoke Type: N\/A\u003c\/li\u003e\n\u003cli\u003eCondition: New\u003c\/li\u003e\n\u003cli\u003eEGR Port: N\/A\u003c\/li\u003e\n\u003cli\u003eFinish: Bead Blast\u003c\/li\u003e\n\u003cli\u003eFlange Shape: 4150 and 4500\u003c\/li\u003e\n\u003cli\u003eFlow Rating: 650 2L\u003c\/li\u003e\n\u003cli\u003eGasket Or Seal Included: Yes\u003c\/li\u003e\n\u003cli\u003eIntermediate Circuit: Yes\u003c\/li\u003e\n\u003cli\u003eJet Extenders: Yes- Secondary Side\u003c\/li\u003e\n\u003cli\u003eMain Venturi Diameter: 1.250 IN\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminum\u003c\/li\u003e\n\u003cli\u003eMetering Block: Billet- Four Circuit IN\u003c\/li\u003e\n\u003cli\u003ePorted Timed Vacuum: Yes\u003c\/li\u003e\n\u003cli\u003ePrimary Power Valve: Yes\u003c\/li\u003e\n\u003cli\u003eRelated Products: 13201\u003c\/li\u003e\n\u003cli\u003eSecondaries: Mechanical\u003c\/li\u003e\n\u003cli\u003eSecondary Power Valve: Yes\u003c\/li\u003e\n\u003cli\u003eSeries: VRS-4150\u003c\/li\u003e\n\u003cli\u003eStandard Vacuum: 2 - 3\/8 dia. and 2- 3\/16 dia\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\u003cli\u003eVRS-4150 Carb 650 CFM 1306\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":52773576868203,"sku":"EDE-1306","price":827.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/EDE-1306-1.jpg?v=1768807415","url":"https:\/\/caautoparts.com\/products\/carburetors-and-installation-kits-ede1306","provider":"CA Auto Parts","version":"1.0","type":"link"}
