5150, 8660 & 8620 cam cores, what is the difference and which is best?

Here is a 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.
