Bob, hopefully this post has lost steam

I talked to Jack Moore(Moore&Moore) over the weekend at the Columbus swap met. He said, he actually ran as good if not better with an old profile cam(R296) in his 572incher.

I still run a 70's Crane it's been in my last 3 motors. I think maybe that the rate of lift in the older grinds was much more severe at lower lifts and could have caused the valve clearance problems.

IMPORTANT!
Crane Cams continuously improves and upgrades its cam designs. In some cases this may mean that two
Crane Cams with the same part number may actually be different grinds. You must check the GRIND
NUMBER stamped on the front of the camshaft and check it against the Grind Number near the top of the
Spec Card.
