My friend and I checked that via a dial guage on the piston top when the heads were off. When we moved the crank, the dial gauge indicated the piston moved. When we would turn the crank clockwise and then turn the crank very slowly counterclockwise, there was no delay indicated by the gauge, indicating to us the chain was not stretched.
Now I have the cover off and I see the chain has some play in it. So I am second guessing myself.
I will try your test, Robert, but I think I will find the chain is just fine. Thank you for the detailed write up.
Of course the chain is stretched, the slack is taken up when the engine is running , but the cam timing has changed some in relationship to piston in the bore , but not enough that you would ever now it ...
Run it ...
