Thanks Crenwelge! That's what I was looking for. Good to hear, that's what I figured. Funny to think that a lot of people nowadays feel uneasy running one at 3,000 for some reason.

3,800RPM would have been about 70MPH, I figure? It's also interesting that even screaming along like that you got 100K out of it before you needed to freshen it up. Again, I kind of have to laugh thinking how many today will very authoritively tell you a 60's half ton wasn't made to go over 55MPH, ha ha. Always interesting to hear from guys like you who found out what worked and didn't in the real world.
