Holley 300-301 Details
Holley now has cast aluminum plenum top options for those of us with limited room in the front of our engine bays. The cast aluminum side mount plenum tops resemble the older Ford EFI manifolds and will allow you to mount the throttle body on the side. This will allow for easier fabrication for boosted applications or for just a different look on your Hi-Ram manifold. Cast aluminum construction designed to mount on our existing Hi-Ram manifold bases. Available in cast or black finish. Models for 86-95 Ford 5.0 Style throttle body patterns in 95mm and 105 mm sizes.
- Designed for side-mounted throttle bodies
- Allows room for designing boosted applications
- Cast Aluminum construction
- 105mm size
- Ford 5.0 throttle body fitment
- Mounts to existing Hi-Ram manifold bases
- Lid has been verified to fit under Cervinis 2.5” cowl hood on 1979-1993 Mustangs with 351W & 302W Hi-Ram bases when using motor mounts that retain stock engine locations.
