Camshaft

The advantages of the 50mm cams are 1) larger base circle so the profile can have more detail, 2) cam companies have some body of experience/knowledge with these dimensions since Pro Stock and NASCAR have been doing this for decades, 3) roller bearings are readily available for this size. There are also some 65 mm cams running around in American auto racing arenas for very specialty applications.

I doubt they look. They certainly are not worth what they cost to install and run.

A lot is made of the "big cams", a whole lot more than they are really worth, and there a lot of really fast cars that do not have one.

Yes, there probably is a little there, IF you have your valvetrain and your combination fully developed. But if you think it's even a tenth, you'll be terribly disappointed.

This is way I ask these questions it sure saves a lot of money. I would like to know more about the the ring package though.

For a stocker or super stocer, yes. There are lots of places to spend money that has better returns.
