NOTE: Camshaft bores No. 2 through 7 do not use a
bushing.
NOTE: The introduction of the storm block increased the
camshaft bushing bore diameter by 2 mm [0.079 in] to
accept a larger outer diameter cam bushing. The camshaft
inner diameter did not change.
NOTE: If the bores without a bushing are worn beyond the
limit, the engine must be removed for replacement of the
cylinder block.
