Mopar Intake Manifold Casting Numbers 1959-1974

Finding the intake manifold casting number is fairly simple. Usually, the casting number is on top of the manifold close to the carburetor mounting pad. Occasionally it's on the bottom of the manifold, which can pose an identification problem if it's still installed on the engine. Due to the very large amount of intake casting numbers, we recommend you use the Galen Govier Casting Number book (part # GGB1) to help you identify exactly what manifold you have.
