Need Your Help

My 1937 Packard Six stopped running while I was driving it to a nearby car show. We were going a steady 55 mph when the engine stopped running. There was no noise, vibration, spewing of liquids, nor any other indication that something was wrong. The engine was at its normal operating temperature, 180 degrees, and the oil pressure was at its normal level, 45 lbs. The ambient temperature was about 90 degrees. The car has been running without any problems. Until Sunday, it started and ran normally, ran smoothly, and had good power. A quick check revealed that there is spark to the spark plugs, and gasoline to the carburetor. I also removed all the spark plugs and they look good; none were wet or fowled. I removed the distributor cap, and all looks good there. It would only backfire through the carburetor when I tried to restart it. My guess at this time is it is a jumped timing chain. I have not gotten into the problem too deeply before soliciting some advice. Any suggestion is welcome. Thanks.
