Coupling this Hi-Ram intake with the high flowing LS7 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!\n\n The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.\n\n Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations\n\n EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.\n\n Cast aluminum construction.\n\n Intended for use on N\/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.\u003cbr\u003e\u003cbr\u003eThese parts should be used for the following applications: Racing\/Performance\/Street Rodder where hood restrictions are NOT a consideration.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cul\u003e\n\u003cli\u003ePort Size ???? 2.49???
