1968 340 timing

To expand on this you can...........

1...Throw the distributor drive gear in blindly not caring where it points

2...Throw the distributor in equally blindly, it will go in 1 of 2 ways, "you don't care."

3...Now bring no1 up on compression, easiest way is stick your finger in no1 hole and crank / bump engine, feel for compression.

4...Bring marks on up NOT to TDC but WHERE YOU WANT timing to be. Look where rotor is pointing "coming to" a tower going CW. This is no1 wire

Retard dist (CW) and slowly bring it advanced (CCW) until points open, or until reluctor/ pickup are aligned.

Plug no1 into that tower, go around CW with the rest, and START THE ENGINE.

Crackedback ^^ above knows his stuff. He has pointed out previously you can SET THE TIMING with a light ON THE STARTER

This entire procedure used to take me maybe 5 minutes.
