INSPECT (Cont)
(1) The top surface of the block
must not vary more than .003
inch transversely and not over
.006 inch, .007 inch or .009
inch longitudinally on the 3,
4, and 6 cylinder blocks
respectively. It will be
difficult to prevent water,
oil, and compression leaks if
the top surface of the block
exceeds these tolerances.
(2) If it is necessary to machine
these surfaces to correct for
the above conditions, do not
remove more than .008 inch of
metal. Stamp the amount of
stock removed on the face of
the block. The distance
from the centerline of the
crankshaft to the top of the
cylinder head surface of the
block must not be less than
16.176 inches.
