Piston Stop - Timing

[dmsfrr]

Checking to see if piston # 1 TDC matches the pulley timing marks can be easily done with the distributor in place.
With all the spark plugs out and the right side valve cover off I used a remote start switch, then a socket wrench on the crank pulley to rotate the engine until cyl # 1 intake valve opened & then closed.
With a finger in the cyl 1 spark plug hole I carefully continued turning the crank pulley (clockwise) with the socket wrench until I could feel the top of the piston coming up the last bit and stop moving, at TDC, which should line up with the timing pointer at the crank pulley.
The rotor will also be lined up with plug wire # 1 on the distributor cap.

Fyi, if there is a gasket of any kind between the distributor housing and block, remove it. It can ruin expensive parts. https://www.ctci.org/distributor-installation/

Depending on which style of crank pulley is on the engine, IF the weight ring has timing marks on it, the ring can easily slip out of position when the rubber layer fails.
