Measure camshaft bore diameter, refer to Figure 5-84. Refer to Table 5-11 for
specifications of the following; camshaft bore inner diameter front No. 1, in block
without bushing, front No. 1 in block with bushing and all except No. 1.
FIGURE 5-84. MEASURING CAMSHAFT BORE DIAMETER
When cylinder block is machined (top deck or crankshaft bearing bores),
the dimension from centerline of crankshaft bearing bore to top deck will
be changed. Ensure that this dimension is not less than 13.302 inches
(337.89 mm). Otherwise, piston may contact cylinder head.
If cylinder block top deck is resurfaced, also measure depth of liner
counterbores. Bore depth must be within 0.234 to 0.236 inch (5.95 to 5.99
Measure cylinder block top deck flatness using precision straightedge, refer to Figure 5-
85. New flatness is 0.003 inch (0.08 mm). If flatness is not as specified, resurface engine
