Holley's new Mid-Rise EFI intake for cathedral-port LS engines

 Modular mid-rise intake for LS1/LS2/LS6 cathedral-port heads.

LS engine swaps don’t always cooperate with hood clearance, especially if you’re trying to transplant one of the taller truck variants into a muscle car with a sleek, low-profile hood. Heck, even some cars with modest cowl hoods have a hard time swallowing the raised truck manifolds on some LS plants. The Holley mid-rise modular intake can handle that problem easily, and now Holley makes it for older cathedral-port cylinder heads. The new piece uses the popular Mid-Rise 2 x 4 intake manifold along with a purpose-built plenum base adapter and a Holley 92mm EFI plenum top which converts it into a Mid-Rise EFI intake manifold. With a max overall height of only 10.44 inches, the Mid-Rise manifold is an excellent choice for street and performance street/strip applications with a powerband from 1,500 to 6,500 rpm. Being part of the Holley modular intake line means that this intake is available as a complete kit with intake, adapter, 92MM top and fuel rails, and all parts can be purchased separately for a custom build up. The plenum adapter (PN 300-231) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.
