[Tigers] k engines

[Clyde McLaughlin]

The crank should have a small extra counter weight just behind the balancer
inside the timing cover,  and the "K"  referrs to the engine letter code in
the chassic number of the car,  don't believe its on the crank,  but maybe it
is...the heads are machined differently for the valve springs,  and hi po is
casted on to the head,  take off the valve covers its easy to see,  Clyde
