Mine has. 234k and I've been putting her thru the test . Usually 80 mph . She is strong and around 6 mpg never skipping a beat ! I have a 62 pd4106 with an 8v71 and she has over a million miles and she also runs strong ! I've never been easy on her in last 5 yrs. so I guess age has nothing to do with it if it's maintained and temps watched as well as keeping oil in them! As house stuff goes just like any other home fix it and keep an eye on all things . Jmho
