CID Heads BE 4.5 LS3 Intake Manifold.

The CID Heads BE 4.5 LS3 intake manifold is designed for engine applications aiming to make 600+HP using LS3 cylinder heads with a single plane intake. The CID Heads BE LS3 intake manifold has an overall height of 9.5" and unmatched HP producing characteristics amongst all cast single plane manifolds. 

This version features the same 4500 square carb pad opening as the 4500 version, with 4150 Holley carburetor bolt spacing, and is designed for classes that must retain 4150 bolt spacing.

*The roof of the LS3 manifold is designed to line up with the roof of a LS3 cylinder head. The port opening on the manifold is not as tall as a factory LS3 port. Testing has shown that leaving the opening on the manifold at its cast height works best. Enlarging the port opening by dropping the floor at the flange to match a LS3 port will reduce taper in the runner and can harm performance.*
