Finding TDC on any engine

1. Pull all the plugs

2. Rotate engine clockwise using a ratchet, with your finger over the #1 cylinder spark plug hole rotate until you feel pressure building in the cylinder.

3. Now screw in a piston stop and carefully rotate crank until the piston hits the stop.

4. Make a mark on the cover or timing tab or anywhere else on the motor, on some 440's with serpentine belt assembly you may want to make a mark on the front of the oil pan.

5. Reverse the rotation and bring the crank back around until it touches the stop again

6. Make your second mark.

7. 1/2 the distance between the marks is TDC
