60 miles per hour all day long

[Gold Digger]

I've read where Ford made the claim that a new model A stock from the factory could run 60 mph all day with out damaging the engine. Has anyone ever done this with a stock engine and drivetrain? None I have ever owned would this. I've had some real good Model A's but I would never try that in one. I had a good 49 Chevy once and it give up on me after about 10 minutes at 60 mph. I went back to flat-head v8's.
