| GM Performance Parts 10051125 Raised Runner Intake Manifold Base (aluminum)
Cross-ram intake manifold is recommended for all maximum-performance competition engines
Designed for raised runner cylinder heads
An air gap beneath the runners insulates the intake charge from engine heat
NOTE: An aluminum plate should be mounted between the runner entries for optimum performance; see the Chevy Power manual for information. This manifold will clear a large-diameter HEI distributor.
