We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common ! Just start by posting a note introducing yourself to the group, that's all it takes here (we don't ask for or retain any personal information here, because our intention is to just "have fun and share information".
I think those 16' Donzi models used small block Ford power, and I'm sure the Secret Service could have contacted a chicken rancher in Texas who could have made one run faster.
You're right about the CC models, they were not in the high performance league, always maintained safety as a rule, and let others go faster. Of course, when it came to racing in the old days, Chris Craft won it all, and apparently did not think they had to prove it all over again. It wasn't until the advent of the XK boats with 300+ horse small blocks did CC get back into the higher performance speed arena.
