Not sure they followed up on the cams use......EPA issues. There were other cams developed. No one is sure, not even the guy who made the cams, if the cams made into the cars.

Lee,

These would have been healthy cams even bigger than Pete's although the lift is smaller. And rollers?? I'd like to see that.
