CAMMOTION PERF

5150, 8660 & 8620 cam cores, what is the difference and which is best? We will break it down with this simple explanation.

5150 Induction Hardened Chromium
5150 is the standard camshaft that most all of our competitors sell. This alloy is induction hardened. While it is not the best available, it is perfectly fine for most applications if proper care is taken to finish the lobes properly.

8660 Induction Hardened Nickel-Chromium-Molybdenum
8660 cam cores have a superior alloy to the 5150 and are induction hardened. This is a step up over the 5150 cam cores.

8620 Carburized Nickel-Chromium-Molybdenum
Our 8620 camshafts are made of a superior alloy to the 5150 and these cores also endure a more involved oven hardening process. This hardening process creates more durable wear surfaces on the lobes while maintaining the desirable ductility characteristics of the the 8620 alloy. The final product is a camshaft that is stronger with a more durable wear surface. Our 8620 cams are a superior product.



Because we know that, for some enthusiasts, pricing is a major factor in choosing parts, we now offer all 3 cam core options. This is an extension of our commitment to make sure that our LS customers can get exactly what they want in a camshaft.

Our pricing for these 3 different cam core choices from Cam Motion is as follows:
5150 $399.00
8660 $425.00
8620 $449.00
