Description

The Holley EFI 300-240 is a cast EFI intake elbow designed to adapt GM LS throttle bodies to intake manifolds with a 4150 mounting flange. It features slotted mounting holes and dual throttle cable mounting bracket bosses, allowing for versatile throttle body positioning (forward, sideways, or rearward). The elbow includes four vacuum ports, a MAP sensor port, and a 100° throttle body angle for increased hood clearance. It is machined and port-matched to a 4150 gasket and has an overall height of 5.12 inches.
