No, it does not run in both directions.

We were trying to see if there was play in the chain. Maybe that is not an accurate way to do it?

We *think* the cam was installed at 112 degree intake center-line. But I do not have the cam card and the engine builder does not remember where it was installed exactly (built the engine over 12 years ago).

The link provides the intake lobe measurements that we took with the gauges installed on the engine. [img:center]https://drive.google.com/open?id=0B47FH99TbpHueDhBRXNweFZrcmc&authuser=0[/img]
