Franz, the local MB indy tech, say an easy 400-450K. Might need valve stem seal or guides before then, but the bottom end is good for a long, long time.

Keep the chain rails from wearing through, replace a stretched timing chain and age weakened tensioner to keep the pistons from meeting the valves. Keep the oil changed and everything else in spec and you should be good to go. Don't let these engines (or any of them for that matter) overheat and you'll be fine.

If getting one with no records, start a set. Start off from scratch by changing all fluids, filters and normal replaceables as well as flcuh the cooling system. Check the chain, rails and tensioner and replace if neccessary.
