Dave & List;
Just to clarify what you said, "...a 300 M crankshaft...", I'm reasonably
sure you meant a crank made of 300 maraging steel alloy-- not one from a
Chrysler 300M...in case there was any confusion on that point. 250M & 300M
alloys are very tough stuff that also has a very simple heat treatment
process.

The secret to thatsituation comes stock in most high performance
motorcycles.
Short sroke and light parts with exceptional material selection.. In a car
size
engine a 300 M crankshaft and Ti rods.. I have run Carillos witha 2.8 stroke
just shy of 11k in a cosworth YB. the pistons didn't like it one bit
though..
Got about 11 or 12 passes out of it and that was it.
