This allows the power valve to operate as it should, based off intake manifold vacuum. A power valve provides further enrichment to the main metering system under load (low vacuum) conditions. Without this external referencing, the power valve would be reading the Supercharger boost pressure, which has no bearing on the engine load.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eProduct Features:\u003c\/b\u003e\u003cul\u003e\n\u003cli\u003eTumble Polished Shiny Finish For Good Looks\u003c\/li\u003e\n\u003cli\u003eManual Choke For Precise Cold Start Control\u003c\/li\u003e\n\u003cli\u003eDual Accelerator Pumps For Add Fuel Under Initial Acceleration\u003c\/li\u003e\n\u003cli\u003eDual Feed Fuel Inlets For Constant High Volume Fuel Delivery\u003c\/li\u003e\n\u003cli\u003eMechanical Secondaries For Perfect Off The Line Launches\u003c\/li\u003e\n\u003cli\u003eLightweight Vehicles w\/Auto Trans w\/High Stall\/Low Gearing\u003c\/li\u003e\n\u003cli\u003eBoost Power Valve For Proper Enrichment Under Acceleration\u003c\/li\u003e\n\u003cli\u003e100% Wet Flow Tested By Holley Technicians\u003c\/li\u003e\n\u003cli\u003eArrives Ready To Run\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Holley (1288)","offers":[{"title":"Default Title","offer_id":52759875059988,"sku":"0-80573S","price":999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/4214\/9396\/files\/17120415_hol_080573s_pri_larg.jpg?v=1783385771","url":"https:\/\/districtmailing.com\/products\/holley-performance-and-race-carburetor-750-cfm-manual-choke-4-barrel-square-bore","provider":"District Mailing","version":"1.0","type":"link"}
