Further proof the cam is crap? I rotated the engine multiple times to verify the numbers. i pushed down on the lifter while closing to make sure it wasn't hanging up.
Take an old pushrod and cut it off just above the deck about a 1/4 inch. Make it parallel to the lifter and stick the dial indicator in the end of the pushrod.
It’s crazy doing it the way you are doing it, and unless you degree cams for a living, you don’t need an expensive tool.
