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 !
Not all projects "are" that simple. The 427 is really not a complicated device, it's pretty well known by now, and the group here has "been there, done that" on many issues. If you have not already converted to Pertronix electronic ignition, consider doing so. It's the nicest thing you can do for your 427, because it essentially tosses the old style ignition points forever. Those points, by the way, are a MAJOR source of missing, hesitation, poor starting, etc., not only in the 427, but in any marine engine. The Pertronix uses a magnetic pickup, and there are many of us who have made the switch very successfully.
The Master Index has a section on Pertronix installation (it's in the 427 section of the Master Index).
I'm glad this one was simple for you, all the best!
