This is from copied a mopar car site P15-D24.com but same engine and is a good explaination of one way to do it


Static Ignition Timing
The classic Catch-22. Your trying to get your flathead started. The engine is not running so you can't check the timing with a timing light. However you suspect the reason the engine won’t start is because the timing is set incorrectly. The solution is easy, static time the ignition.

You need a cheap neon indicator, the kind you use to check your household wall outlet. First turn the engine over by hand until the timing marks line up at top dead center (TDC). Pull the distributor cap and verify the rotor is pointing at the cylinder #1 plug tower on the distributor cap. Usually the rotor is pointing around 7:00 o’clock. If not, it means cylinder #6 is in firing position and you need to turn the engine one full revolution. One way to be sure of the firing position is to pull the front valve cover off and watch the lifters. If cylinder #1 is TDC, both valves will be closed. As you continue to turn the engine manually, the exhaust valve will open. Once TDC is set, pull the plug wire off plug #1 and hook up one lead of the neon tester to the plug connector. Connect the other neon lead to a solid ground, such as the coil bracket. I use short jumper wires with alligator clips to secure the connections.

Reinstall the distributor cap, and loosen the locking bolt on the distributor so it will rotate. Turn on the ignition. Rotate the distributor fully clockwise until you hit the stop. Then slow turn counter-clockwise until you see the neon tester flash. When the light flashes you are set for TDC. Tighten the distributor locking bolt. The advantage of starting with static timing is neither the vacuum or centrifugal advances are in use. By the way, this procedure is similar to one discussed in the Plymouth Service Manual in the Ignition System section. The service manual setup uses the ignition point circuit instead of the plug wires and a six volt bulb is used instead of a neon test light.


Road Timing
A reader recently shared a story from his grandfather about the red neck method of road timing a flathead. One guy drives in circles in an empty pasture while the other guy is holding on for dear life under the hood with screwdriver in hand. The reader had seen photos of this in a local diner, and indicated you don't really grasp the hilarity of the situation until you see it, complete with several barking dogs in pursuit of the vehicle in question !

Road timing, a common practice for flatheads, need not be a danger to life and limb. The procedure is discussed in the factory Service Manual in the Ignition System section. You "road time" when you advance the ignition timing up to 4 degrees BTDC. Usually this makes the car more responsive. You know you have advanced the timing too far when the engine starts to ping or knock under load (i.e. out on the road). Then you retard the timing a couple degrees. Best news is you don’t need a helper holding onto the hood !
