Just an anecdote or two to add about the Pro-stock class.
-My Dad was the first guy to run a cat in the class(1980)
-His 30 Shadow Cat "Black Duck" was faster with twin 2.4's vs. the other guys running triples
-in '82(I think), "Fox," a 30' Velocity showed up with the new Steve Stepp pad bottom. It had triple Johnsons on the back and was now the fastest boat in the class. The next race, my Dad showed up with a 3rd motor and everyone said "oh chit."
-Lots of different types of boats/motors ran in that class. "Special Edition" was a 30 Shadow cat with small blocks. "Rolling Thunder" was a 32 Cobra with I/O's. Then you had the Tritons show up around 82. They were faster with triple OB's vs. the Shadow but could not handle the rough water. When my Dad retired, I think he won 29 out of 41 races. A winning percentage that we believe still stands to this day.
-Black Duck was sold to Nicky Cutro in '85(who still services our family's 3 boats). He wrecked that thing many times(flipped, burned, stuffed) but still won more championships. We believe it is the winningest boat of all time.
