This is the .509 cam I removed from the 440. It has maybe 1500 miles on it. As you can see there is a flaw on the lobe. The corresponding lifter is also pictured, and looks perfect. This is the closing side of the lobe. My machinist, who has never steered me wrong, says it is fine to run. I have never been one to reuse a cam, even if it is perfect, so I am reluctant. My kids want to use it, mainly because the money to replace it would have to come from some other part of the project.

Would we be crazy to use it?
