Man, I cant see much about this thing that makes it a "project boat". Looks pretty nice to me! A heck of a lot nicer than some of my daily drivers, ha. Very cool boat with a very cool heritage. Big block Mopar, nice!
Personally, I'd put some ATF in the cylinders and let it sit for a few weeks. Then spin it over by hand, nice and easy. Throw a fresh tune up at it, change the fluids... and then get it running. If you can get it on the water and moving under its own power, that will tell you a LOT about what the boat needs. It will tell you what it doesnt need right away as well! There are way too many things that are just unknown regarding the powertrain (from carb to prop) that you just cant verify without putting a load on it. A quick water test will direct your wallet as to what gives you the best bang for your buck.
