Re: deck,stringer rebuid underway
Wow that engine looks . . . impressively destroyed!
You seem to be going in the right direction. I would rebuild the stringers in the basic original configuration. While you might add a few braces etc, anything that is a significant design change is being done without the benefit of being able to stress analysis. Your hull with the stock stringers in good condition was seaworthy so to speak. You might build a stronger substructure that stresses the hull in a manner different than the design.
As to the truck 350
You would need a marine cam, brass freeze plugs, marine compatible gaskets and of course marine cooling system.
Accessories such as the alternator need to be spark protected for use in a marine environment. Marine water pumps tend to have different bearings and be bidirectional. Fresh water cooling systems on boats are more corrosive than antifreeze is in a car cooling system. Carburetors are different and don't use vacuum ports and so on and so forth.
Using the accessories off the old engine is going to save a ton of money if they are usable. Given the condition of the engine, I doubt you'll be able to salvage anything from the long block, but brackets and the fresh water water pump should transfer over.
marinizing an automotive engine is expensive, buying a boat with a running engine and a bad hull might save you a bunch of money.
i had a deal with a friend, i help him build a fence 200ln ft and a shed and i can keep my boat there for a year.. so 3 months later know that the fence is up and im spending all my time on the boat and not on his house he wants me out!!!!
