RE: "Big" Hydro Resources
Nope, it was only the cabover in 1970. After the 1970 season, crew chief Jim Lucero converted the boat to a front mounted Merlin engine with the cockpit arrangement you are familiar with. There were some changes made by the Budweiser crew after they received the boat after the 1972 season, but nothing in the general appearance other than going from an orange/gold paint job to the gold/red/white paint the Miss Budweiser sported through the 1994 season.
