Coupling this Hi-Ram intake with the high flowing LS1\/LS2\/LS6 style cylinder heads has outstanding potential for N\/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e• Plenum Top Gasket Type - 3\/32” Round O-ring Cord\u003cbr\u003e• Runner Length - 6.58” As-Cast Runner Cross-Sectional Area - Tapered 4.25 in² to 2.53 in²\u003cbr\u003e• Mounting Flange Gasket Type - Standard LS3 Molded O-ring\u003cbr\u003e• Port Size - 2.49” H x 1.21” W\u003cbr\u003e• Black color\u003cbr\u003e\u003cbr\u003e\u003cem\u003eThese parts should be used for the following applications: Performance, Racing, and Street Rodder where hood restrictions are not a consideration.\u003c\/em\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":48275907018979,"sku":"300-227BK","price":1946.2,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/0821\/9875\/files\/542f492008cc50f3a57f83085c74a2aa.jpg?v=1771069716","url":"https:\/\/fastlanespares.co.nz\/products\/holley-300-227bk-hi-ram-lower-manifold-gm-ls1ls2ls6","provider":"Fast Lane Spares","version":"1.0","type":"link"}
