Are you Having a problem with starting the car when hot?
Starts up no problems in the morning or a cold start. After driving it awhile and parking it, come back to the car 15 or 30 minutes later to start it, Cranks once then stops turning, kind of like it has a dead battery. Leave the car alone for another 20 minutes or more and it starts up again.
Yes this is very typical of these older cars I'm speaking specifically a 430 CID Lincoln, Mercury or Ford..... it certainly happens with other engines as well.
1-Be sure your timing is set correctly.
2-If Needed, Replace your Battery. I have fitted a larger battery with more cranking Amps.
3-Replace Starter and battery cables. Use a large gage where possible. Do not use those quick repair bolt on terminals. This is the number one cause of slow cranking.
4-Replace the ground strap to the fire wall. You may want to Install an additional ground strap from the engine to the firewall or to the frame.
5- You can add a heat shield to the starter as well as slipping the starter cable through a piece of hose as added heat protection for the cable.
6-Adjust you idle at least 700 RPM I have mine at 800 RPM
7-Check your main thermostat. Is it at the specified temperature? You may need to pull the water pump and remove the two smaller thermostats in the block. They go bad quite often.
8- You can also replace the fan with a flex fan for additional cooling.
9- One more thing I noticed. In the distributor the vacuum advance will stick in the advanced position. Be sure the advance is working correctly.

You will need to Remove the distributor and thoroughly clean it. Be sure the plate rotates smoothly.
