    Aggressive Cast Hi-Ram Intake Manifolds!

    With the aggressive race-bred style of the Holley GM LS Modular Hi-Ram Intake Manifold, there is no hiding what you intend to do! This cast aluminum intake has been designed to be an alternative budget-minded solution to fabricated sheet-metal intakes on extreme-performance engines. Intended for use where hood clearance is not a factor this intake features straight 6-1/2 in. long runners with an overall height of just over 11 in. to produce max power on naturally-aspirated or forced-induction engines using high-flowing cylinder heads at 7,000 to 8,000 RPM! With a modular base design that allows you to use carbureted or EFI systems and choose or fabricate your choice of top plates, the Hi-Ram LS intake is perfect for any LS-powered drag race, muscle car, marine, off-road, sandrail, pulling truck or street-rod application!

     

    Are these the ones used for the cathedral port heads?
