have you ever seen this before

I gues it kinda makes sense in that the 2 cylinders are inline in the firing order. cylinders 7 and 2. if they were in the right position, both of the valves would be closed therefore not ingesting any fire caused by the burning fuel. I guess it depends how fast the engine was shut off after the fire occured. Im surprised that the guy that had the car was that lucky that the car did not burn to the ground. this is all a guess but I did have a similar thing happen to me while I was driving a friends car. Double pumper holley on a 67 charger with a 440. backfired at a light taking off and the engine stalled. fuel kept coming and fire started under hood. Lucky a dump truck driver nearby handed me his fire extinguisher after he stopped his truck.
