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 !
I am at Kentucky Lake for a Lucas Oil Drag Boat event. I drive a 1/4 mile Top Eliminator (9 second) Alcohol Hydro. It is my father's team and I also help build and tune the engines and ignition system.
Regarding the intake, next time you are on your boat take a close look at the carb and intake and let me know if the angle of the carb flange is the same as the angle of the valve cover gasket surface. I am almost certain that mine are angled to level out the carb, which is done with angled spacers on more modern inboard marine engines. Now you have me wondering about mine. I agree, they have a Ford casting number.
