The 930 I have been working on has really been a surprise. The pan and heads had never been off till now. 65 is the date stamped on the bearings. No cracked heads or rings even though he said it had gotten hard to start and starting fluid has been used regularly. It has been using a far amount of oil. The brgs show a little copper but crank looks great. The heads do need valves and guides. It has about 8500 hrs the owner guesses as the tack cable was broke for a while. He is the 2cd owner and has had it for about 12 yrs. I posted a pic of the pistons because I really had nothing else to show. It will be getting new sleeves and pistons Rod.
