Possibly the hottest new item for the 8.2-deck small-block Ford at the 2019 SEMA Show is Holley Performance Products’ new side-feed Hi-Ram intake manifold for the 289/302 Windsor series engines. Available with provisions for OEM–pattern Fox-body throttle bodies up to 95mm in diameter, this manifold has been designed to fit under a 2.5-inch cowl hood on an ‘87-’93 Mustang.
Made from cast aluminum, the straight-shot runners have been designed with a runner-length and tapered cross-section designed to provide huge gains in the upper-RPM range on a variety of EFI 5.0-liter based engine combinations. In addition to the manifold, a set of aluminum fuel rails with -08 feed and return ports machined for the OEM EV1-type injectors.
The top half of the manifold is removable allowing for easy access to the inside of the manifold, which could be useful in custom power-adder applications, and is sealed with a 3/32-inch O-ring to withstand copious amounts of pressure. While the version shown here is a pre-production fabricated lid, the manifold ship with a cast aluminum lid, which is also available in a front-feed design, if that works better for your application.
While the manifold will require the use of a low-profile distributor, Holley offers two suitable models making this a complete package that will work on everything from a stock-ish engine bay to a tube-framed racecar. According to Holley, since its announcement a month ago, the manifolds have sold out twice, proving that the small-block Ford market is alive and well and still hungry for awesome new parts.
