These new intakes are available to fit oval or rectangular port heads, and 4150 or 4500 style throttle bodies.  These Intakes are ideal for converting your big block high performance or racing engine from carburetion to fuel injection.  These intake manifolds were computer designed and dyno proven to produce more horse power and torque than other EFI manifolds.  Each manifold package includes anodized and laser etched fuel rails, and two sets of mounting brackets (brackets allow use of 1.48\" or 2.56\" O-ring to O-ring injector lengths).\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen plenum\/single plane design\u003c\/li\u003e\n\u003cli\u003eNo EGR provisions\u003c\/li\u003e\n\u003cli\u003e3500-8000 RPM power band\u003c\/li\u003e\n\u003cli\u003e4150 carburetor mounting flange\u003c\/li\u003e\n\u003cli\u003eIncludes fuel rails and mounting brackets\u003c\/li\u003e\n\u003cli\u003eDesigned for today's larger cubic inch big block Chevy race engines\u003c\/li\u003e\n\u003cli\u003ePerfect for hard core drag racers in the NHRA Super Comp, Super Gas, and Street classes as well as IHRA Quick Rod, Super Rod, and Hot Rod categories\u003c\/li\u003e\n\u003cli\u003eRectangle Port Dimensions: 2.28” High x 1.48” Wide\u003c\/li\u003e\n\u003cli\u003eHeight: Front 5.96\", Rear 5.96\"\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eApplication:\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eYear\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSubmodel\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eEngine Size\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUniversal\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eSpecs:\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eHolley EFI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eCast\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEmission Code\u003c\/th\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003ctd\u003eChevy Big Block V8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManifold Type\u003c\/th\u003e\n\u003ctd\u003eHigh Rise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eEFI Manifolds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRPM Power Band\u003c\/th\u003e\n\u003ctd\u003e3500-8000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003eLimited 90 Day\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":32596744831025,"sku":"300-563","price":571.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2493\/0960\/files\/holley-efi-intake-chevy-big-block-v8-efi-300-563-modern-day-muffler-1.jpg?v=1739186389","url":"https:\/\/moderndaymuffler.com\/products\/holley-efi-intake-chevy-big-block-v8-efi-300-563","provider":"Modern Day Muffler","version":"1.0","type":"link"}
