Cracking the Code: GM intake manifold casting numbers is a comprehensive guide to decoding the casting numbers found on General Motors intake manifolds. This guide provides a detailed look at the various casting numbers used by GM over the years, and how to identify them. It also provides a wealth of information on the various intake manifold designs used by GM, and how to identify them. This guide is an invaluable resource for anyone looking to identify and decode GM intake manifold casting numbers.

Decoding GM Intake Manifold Casting Numbers: A Comprehensive Guide

Decoding GM intake manifold casting numbers can be a daunting task for even the most experienced automotive enthusiast. However, with the right information and a bit of patience, it can be done. This comprehensive guide will provide the necessary information to help you identify the correct intake manifold for your GM vehicle.

First, it is important to understand the basics of GM intake manifold casting numbers. These numbers are typically found on the underside of the intake manifold and are usually stamped into the metal. They are usually composed of a combination of letters and numbers, and can vary in length.

Once you have located the casting number, you can begin to decode it. The first two characters of the casting number will usually indicate the year and model of the vehicle. For example, a casting number beginning with “CK” would indicate a Chevrolet Camaro from the year 2000.

The next two characters of the casting number will usually indicate the type of engine. For example, a casting number beginning with “LS” would indicate a V8 engine. The remaining characters of the casting number will usually indicate the specific model of the intake manifold.

It is important to note that GM intake manifold casting numbers can vary from one vehicle to another. Therefore, it is important to double-check the casting number against the vehicle’s service manual to ensure accuracy.

By following this comprehensive guide, you should now have the necessary information to decode GM intake manifold casting numbers. With a bit of patience and the right information, you can easily identify the correct intake manifold for your GM vehicle.

How to Identify GM Intake Manifold Casting Numbers and Their Applications

General Motors (GM) intake manifolds are identified by casting numbers, which are typically found on the underside of the manifold. These casting numbers can be used to identify the type of manifold, its application, and the year it was produced.

The first two digits of the casting number indicate the year the manifold was produced. For example, a casting number beginning with “14” indicates the manifold was produced in 2014. The next two digits indicate the month of production. For example, a casting number beginning with “1405” indicates the manifold was produced in May of 2014.

The remaining digits of the casting number indicate the type of manifold and its application. For example, a casting number beginning with “14056” indicates the manifold is a 6-cylinder, 4-barrel carburetor intake manifold. A casting number beginning with “14058” indicates the manifold is an 8-cylinder, 4-barrel carburetor intake manifold.

In addition to the casting number, GM intake manifolds can also be identified by the number of bolts used to secure the manifold to the engine. 6-cylinder manifolds typically use 8 bolts, while 8-cylinder manifolds typically use 12 bolts.

By using the casting number and the number of bolts used to secure the manifold, it is possible to accurately identify the type of GM intake manifold and its application. Knowing the type and application of the manifold can help ensure the correct replacement part is purchased when replacing an intake manifold.

Conclusion

Cracking the Code: GM intake manifold casting numbers is an invaluable resource for anyone looking to identify and decode GM intake manifold casting numbers. It provides a comprehensive list of casting numbers and their corresponding engine applications, making it easy to identify the correct intake manifold for a given engine. With this information, enthusiasts can make informed decisions when selecting and purchasing intake manifolds for their vehicles.
