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 went back and looked at your earlier photos and I see clearly this is a flywheel aft (F) motor with distributor aft as well as we would all expect to see. At some point the power for these 23' Lancers transitioned to the Q series and then all bets are off regarding rotation, etc.
Since this is an F motor I think you have the option to install the aluminum Edelbrock Performer intake, that Wes indicated he liked very much, so that's an option now and later too. I am considering such a swap, already have one on my 327H powered wood speedboat and it works well.
The Essential Guide indicated the a 283 or 307 with no designation regarding whether it was an F or Q motor, but this one is clearly an F from the photos. My question is did you replace the long block with a 283, 307, 327, or 350 and if so, do you know what compression ratio you will be running ?
Really good to see you are making this kind of progress, will be a new boat when you're done, would cost $60,000 or more new on the showroom floor.
