PRODUCT DESCRIPTION

The CID Heads BA LS7 intake manifold is designed for engine applications aiming to make serious HP using LS7 cylinder heads with a single plane intake. Designed with extensive use of Computational Fluid Dynamics the manifolds are available in 3 Cross Sections at the runner opening in the plenum. 4.0", 4.5" and 5.0" Square Inches of Cross Section. These numbers refer to the size of the runner opening in the plenum where the runner begins to head down to the cylinder head. The bigger the number the bigger the opening and more taper in the runner from the opening to the cylinder head flange. 

The 4.0" Cross Section Version is suited to smallish close to stock cubic inch builds making up to around 650HP to 700HP.  The 4.5" Cross Section Version is suited to mild 400"+ builds with hydraulic roller or small solid roller cams looking to make up to 800HP to 850HP. The 5.0" Cross Section Version is for those more serious builds looking to exceed 850+HP.

The CID Heads BA LS7 intake manifold has an overall height of 9.5" and unmatched HP producing characteristics amongst all cast single plane manifolds. It features a square carb pad designed to suit a 4500 Dominator carburetor or a 4150 Holley.
