I have no idea of the milage. I have had it about 10 years. I put in a aftermarket speedo and it has about 1000 miles. Inside the engine looks clean . I change oil and filter about once a yearand used 10w40 lastime. someone said that a 30 hd may be better,it has a elect guage plumbed like it shows in shop manual.engine runs around 180 when driving.block id says its a 57 . i found a tag on the motor mount that said it was rebuilt and bored 40 over but no date.
