The manifold is designed to work with 4150 Style Throttle body EFI systems like the Holley 4150 style 112-587 and 112-588. 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 overall height than most single plane manifolds, and a choice of two distributor clamp locations. The isolated design of the air\/fuel passages helps to increase charge air density and performance. The fuel injector bores have back-cut exits in the runners for better fuel atomization. This design points the injectors at an angle to match the intake runner airflow angle. The black coated fuel rails and rail bracket assortment are included with the manifold for any easy installation with the injectors that you choose to use for your combination. Fuel rail designed for maximum throttle lever clearance.\nIts low profile and single plane design are ideal for Sniper \/ Terminator TBI installations (dual planes aren't ideal for EFI)\nVortec Intake fits most popular GM crate engines equipped with Vortec or Fast Burn Heads including HO engines (like 350 HO), SP Series Engines (SP 350) and ZZ Series Engines (ZZ6).\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSingle plane design with isolated plenum to keep the air charge cooler\u003c\/li\u003e\n\u003cli\u003e4150 square bore mounting flange to adapt most aftermarket throttle body designs\u003c\/li\u003e\n\u003cli\u003ePower band: 2500-7500 RPM\u003c\/li\u003e\n\u003cli\u003eHeight: Front 4.23\", Rear 5.33\"\u003c\/li\u003e\n\u003cli\u003ePort Size: 2.05” height 1.02\" width\u003c\/li\u003e\n\u003cli\u003eLower throttle body mounting height to help with hood clearance\u003c\/li\u003e\n\u003cli\u003eBlack coated fuel rails with bracket assortment allowing different height fuel injectors\u003c\/li\u003e\n\u003cli\u003eFuel injectors are not included\u003c\/li\u003e\n\u003cli\u003eFuel rail designed for maximum throttle lever clearance\u003c\/li\u003e\n\u003cli\u003eSmall Block Chevrolet 262-400 cid engines equipped with 1996-2002 (L31) Vortec cylinder heads (non-EGR applications)\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 Aluminum\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\u003eChevrolet Small Block Gen I\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eSatin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront Height\u003c\/th\u003e\n\u003ctd\u003e4.18\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFuel System Type\u003c\/th\u003e\n\u003ctd\u003eEFI\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\u003eRear Height\u003c\/th\u003e\n\u003ctd\u003e5.28\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRPM Power Band\u003c\/th\u003e\n\u003ctd\u003e2500-7500\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":32596773863473,"sku":"300-263","price":628.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2493\/0960\/files\/holley-efi-sbc-4150-single-plane-fuel-injection-intake-manifold-300-263-modern-day-muffler-1.jpg?v=1739186389","url":"https:\/\/moderndaymuffler.com\/products\/holley-efi-sbc-4150-single-plane-fuel-injection-intake-manifold-300-263","provider":"Modern Day Muffler","version":"1.0","type":"link"}
