1955-1964 Corvette Exhaust Manifold ID

All early Chevrolet Corvette factory exhaust manifolds are cast iron. Since the manifolds are cast, the actual casting number and date are raised above the actual surface of the part. Most casting numbers are visible when the manifold is installed on the engine. The casting number location and casting date location will vary from year to year and sometimes manifold to manifold. Some manifolds will not carry a casting date at all. Small block manifolds do not carry a year designation. 2" outlet small block manifolds will have a casting date, while most 2 1/2" outlet manifolds do not have a casting date. There were two types of manifolds being cast for Corvette, the first from the Flint, Michigan built engines, which were cast in Saginaw, Michigan. All small block Corvettes used these manifolds. The second type was cast at the Tonawanda Engine plant and all Corvette big block engines used these manifolds. The big block manifolds will be discussed and identified in the second installment of this article.

Classic 1955-65 Corvette Camshaft ID

The camshaft is the one part of the internal combustion engine, which has the most bearing on how that engine will operate. The basic function of the camshaft is to control the timing, the length, the speed, and the height of the intake and exhaust valve openings inside the cylinder head. The camshaft in all Chevrolet engines is located within its own bearing chamber below the cylinder head face and above the oil pan rails. There have been some minor changes in rear camshaft bearing face design, but for the most part the camshaft has remained the same from 1955-82. It is important to verify which type of block, rear bearing face and camshaft bearing you need before you invest in a camshaft.
