right (i'm a clinical surgeon, but i've always thought sir isaac newton was
the greatest of our predecessors), and somewhere, i remember reading that
rods/pistons start to come apart when acceleration exceeds 25,000
feet/sec**2, and longer stroke means greater peak acceleration of parts at
given rpm, therefore, lower revs achieved before acceleration starts to rip
rods apart
