John described it
well.
More modern
? Use a test light...
I would do the distributor while it
is off the engine to set the point gap on a high
distributor cam lobe. It is easier than
leaning over into the engine compartment.
Set the engine for number one cylinder at
the top of compression stroke.
Put distributor in, and find the advance
you want, like 7 to 10 degrees before top
dead center (BTDC). Put a test light from
power source to the distributor and
rotate the distributor until the light goes out. That is when the contacts "open"
and when the coil should fire that spark plug.

First you have to be sure you are on the
compression stroke of the number one cylinder, either by feeling the air push
out of the cylinder with something to cover the spark plug hole or by pulling
the valve cover and watching the valves to be sure both are closed on number
one when the timing mark lines up with 10 degrees or the correct timing for
your engine. Once you have the timing mark lined up you can use cellophane off
of a pack of cigarettes to put between the points which you will pull gently
on while you turn the distributor opposite of rotation until the points
release the cellophane and tighten the distributor bolt to lock the
distributor in place. Of course you have to have the rotor pointing at number
one and the distributor all the way in for this to work. You also want to be
sure the points are gapped properly before you set the timing.

Subject: [FWDLK] Timing a 331
Hemi
Hi Every one I am trying to
start the 331 hemi I just had rebuilt and wanted to ask if anyone had any
tricks to setting the timing with the engine not running to start me
off. I read the book and it is confusing as to the proper way to do
it. I think the book wants 10 Degs BTDC but if anyone has a more modern way
of efficient way of doing it . I would appreciate the help. I
have 3 weeks to have the car back together before the first car show of the
season in Plattsburgh NY Thanks again for the help. Chuck
