Product Description
Holley Hi-Ram LS3 Rectangle Port Intake Manifold with Fuel Rails - Black Finish
Fits Head Castings 823 821 5364 and Aftermarket Rectangle Port LS3 Style Heads
The Holley Hi-Ram EFI Intake Manifold was introduced as a cost effective alternative to fabricated sheet-metal manifolds for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing rectangle port LS3 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Runner lengths and port taper are designed to work for a wide range of engine configurations. The included fuel rails are machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. Build maximum performance with EFI LS Hi-Ram intake manifolds from Holley.
