First, I congratulate Downunder for having fun. As I see it, the virtues of an ABC include a quick breakin, and ability to run hard without damage. But I have a couple of questions. If there is a problem with piston-liner friction when run rich, wouldn't there be a heat build up? If there is no heat build up, as shown by Downunder's numbers, is the friction happening?

Secondly, and more importantly, name me a current model of car which needs any special breakin running. I remember 50 years ago when you were supposed to run a new car at varying speeds, and not go too fast, but that's not the case any more, at least not with Ford products..
