Holley 300-126BK Details

This manifold is modular, and the plenum adapter (PN 300-267) will accept all of the popular Holley LS Hi-Ram plenum tops as a foundation for custom induction systems.
The Modular Mid-Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake manifold along with a purpose built plenum base adapter and a Holley 95MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold. With a max overall height of only 10.44", the Mid-Rise manifold is an excellent choice for street and performance street/strip applications with a power band from 1,500-6,500 RPM and limited hood clearance. It's perfect for turbocharged, or normally aspirated applications.
*** The front and rear height measurements listed in the Specs section are referencing the overall height with the top plate installed. Please see the diagrams in the product images for other dimensions.
