Engines that you have loved and blown

[Larry Colen <lrcar@red4est.com>]

Does anyone have pointers to _QUANTITATIVE_ data on the effect of
different treatments of steel? 

I'm aware that cryo treating gives a smaller grain size than heat
treating, and that nitriding is only skin deep. I haven't had anyone
point me to any quatitative data on the changes in strength or failure
rate from the different techniques.

I also don't know how much a stock crank needs to be strengthened for
various conditions. How over, or under, engineered is it?
