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 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.
