Description

It offers outstanding potential for naturally aspirated and forced induction engines, particularly when paired with high-flowing LS1/LS2/LS6 style cylinder heads. This manifold features aggressive, race-bred styling suitable for drag racing, muscle cars, marine, off-road, sandrails, pulling trucks, track, and street-rod applications.

The base of the Hi-Ram is modular, accepting various carbureted and EFI tops, and serves as a foundation for custom induction systems. The EFI fuel rails are equipped with –8AN O-ring fittings, designed for high fuel flow and to dampen pressure pulsations. Construction is cast aluminum.
