Maybe some have seen this, I found this on the McCulloch VS-57 site

Some might say that this is an unusual choice for the racing McCullochs section of the site, however the first of the four 1954

Packard Panthers produced was raced at Daytona in 1954 turning an average of 110.97 mph, based on runs of 111.24 and 110.70 mph. More significantly in a later one-way run, using a racing type of windscreen instead of the standard windscreen, which was not officially timed, Dick Rathman claimed that he had clocked himself through the traps at131.1 mph. The Panther was Packard's first fiberglass-bodied car and was produced as a show car. Built on the 122" wheelbase, it used the 359 cubic inch straight eight engine of 1954. Boost was provided by a McCulloch which provided 275 horsepower.
