Doug - My point was that "crank flexing" is the least of our worries
about our Vanagon engines!  There are NO crankshafts that are made of
magnesium OR aluminum.  They ALL are of steel.  An antique Buick
"straight-8" supported by THREE main bearings is fully capable of
handling 6,000rpm, back in '65, while properly balanced, should indicate
that a four-cylinder VW motor is more than capable of doing the same.
