The Edelbrock Victor Junior 302 Intake Manifold is designed for competition engines using modified stock cast iron or aftermarket Windsor-style cylinder heads such as the Edelbrock heads #60259 and #77169. The intake manifold directs the air or air-fuel mixture from the throttle body to the intake ports in the cylinder head. The flow typically proceeds from the throttle body into a chamber called the plenum, which in turn feeds individual tubes, called runners, leading to each intake port. The height of the intake manifold is 5. 5. The Victor series manifold delivers race-winning performance for competition engines.
