Very cool! Love that old stuff. Didn't realize how big those V-12's were until I was in Ken Warbys basement bar one time and he had a piston as an ash tray. He owned one of the piston driven Miss Budwiesers as a toy for a while until seeing how fragile those motors were in that configuration.
That show did another episode where they were racing for the McCulloch O/B factory team.
How many stop to realize where we started and how we got to where we are today?
