On my motor one cam gear tooth is 18 degrees. But it is only 9 crankshaft degrees. So I I'm a tooth off I'm off 9 degrees. This was easy in my case due to cutting the block and head. The marks were wrong in either direction. Had to move the cams a bunch to get them both straight up. With 2 cams it is harder because you line up the intake, but that doesn't mean the exhaust is right. I was running for a year with my exhaust cam 9 degrees (one tooth) retarded.

Art; I thought that I understood this,but now I am confused. You state 10 crank degrees equal 20 cam degrees. Since the cam moves half of the crank,wouldn't 10 crank degrees equal 5 cam degrees? help to explain
this please. ed
