Cheers, Danny.
Maybe something that's more of a numerically connectable CO-inky-dink with the "550" is the "547" Fuhrman twin-cam design project that was numbered at about the same time (but developed separately). Co-inky-dinkally, when each project found the other, their fame became mutually codependent.
