318 marine stuff goes for good money. Did you get any distributors? Cranks can be made to work by polishing the grooves out, and they are usually premium shot peened forgings. The 360 should be a premium casting. The 4 barrel intakes also work well and are sought after. Were they run in salt water?
Look pretty clean , I would suspect fresh water, All these came from the St Louis area. Unfortunately the 360 block needs at least one cylinder sleeved.
