Guess my age! I mean mileage!!

Engine is a 5.9 I just picked up, I was told, it had 50xxx miles on it lol, but I’m starting to think 150xxx more like it tell me what you guys think!

I still see the crosshatch on all cylinders, the valve seats don’t look sunk but I’m no expert, and cam bearing look great take a look!

Valves look good. Two years ago I sold a 75' 360 with 53,000 miles on it that came out of my friend's camper in Florida. So, I say it is possible. I'm still waiting for the balance, $100.00.
