No idea how meny miles it had, since the odometer was broke when I bought it. About 8 years ago, I had to get a valve job done on it, so it lasted at least 33 years, most of them on unleaded. A leakdown test showed that exhaust valves weren't sealing properly. After new valves, guides and seats, the motor was back to normal, at least until I sold it to my brother. -- Tony tony@xxxxxxxxxx =========================================================== INSTANT CAR INSURANCE QUOTE!
