Who has the Highest Mileage Slant-6??

I can not officially confirm my mileage as my speedo broke long before I got it. I spoke with the original owner who told me in 72 when it was sold he had ALOT of miles He thought it was around 150,000. The woman that bought it from him registered it till 93 so say 10,000 a year which would be low. Would be 210,000 so roughly 360,000 miles. The engine had been rebuilt at least once before I got it. I rebuilt the top end last year and she is now running like a dream.
