Don,
While you were tearing up the east coast, Jack Mendenhall and company were tearing it up on the west coast. The Pea Soup dragster was originally fitted with a hopped up Ford flathead V-8 the way it is shown now. Later they switched to a Cadiallac engine, which was taken out and put in something else. When it was restored as a tribute car, they put a flathead back in. Here are the specs for those of you than can appreciate them.
The race photo above shows the special on the right at the drag track in San Luis Obispo.
