What to look for in a 60's buick V-8?

From the description of the engine and the boat (trihull)  I'm kinda guessing either 300 or 350 Buick.  I've seen a few similar boats with these in them.  What outdrive is on the boat?  I would bet OMC Stringer Drive.   Also, what year is the boat?  There should be a series of numbers stamped into the right side of the transom up near the top, when you are standing outside the boat.  The last two digits are the year.  That will help pinpoint what series Buick it is.  I'm thinking mid to late '70's.
