camshaft chain

[wings]

How can you tell if the camshaft chain is stretched on a '72 600?

This is an article I put together a number of years ago, it talks about replacing the cam chain without pulling the engine, head or cylinders.  You don't have to start your engine but by pulling one of the plug wires you can turn the engine over with the starter without starting.  This will make the hydraulic tensioner in the bottom of the cylinders tighten up and give you a better idea of how loose the cam chain is.
