CID Heads LS3 5.0 4500 Carb BA Intake Manifold.

The CID Heads LS3 5.0 4500 Carb BA intake manifold is designed for engine applications aiming to make 850+HP using LS3 cylinder heads with a single plane intake. The 5.0" intake is also suited where port openings at the cylinder head will have more than 3" CSA, allowing for the taper percentage to be kept at a desired amount. The CID Heads LS3 BA intake manifold has an overall height of 9.5" and unmatched HP producing characteristics amongst all cast single plane manifolds. 

*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 and matching the sides works best. Enlarging the port opening height at the flange will reduce taper in the runner and can harm performance.*
