must be a good reason that the OEMs use it."

1) It's light and won't yank the crankpins off the crank at 6000rpm.
2) It's much easier(read cheaper) to machine than steel.
3) You were correct about the rest, except than combustion temps can
reach upwards of 4400 F(transient, but hot). Not bad for a calibrator;
with some training, you be a decent piston engineer.
