You're best off looking for a 4 bolt main truck block and crank of the same vintage if you're going to traipse down that path. ...

Re: 350 chevrolet replacement

Considering that 86 was the transition year, you'll Need to Know which crankshaft seal yours has, 2-piece(older), or the 1-piece(newer).....<br />4-bolt mains are Really Unnessessary in a boat motor.... Only the High Preformance motors use them...... Chevies have a Very Durable Lower End.... MOST Merc.s come from the factory with 2-bolt mains,+ Cast Pistons.....<br />Go to your nearest Machineshop or Junkyard,+ get a motor Exactly like the 1 you have Now.... That's the Easiest Way....
