GENERAL INFORMATION
The 4.5" bore, V8 (Direct Injection) Engine can be reconditioned to
provide performance characteristics comparable to a new engine. The
reconditioned engine will operate satisfactorily if certain reconditioning
precautions are observed.
Performance and oil control comparable to a new engine can be
obtained only if the necessary machining is done to the required
Specifications. Cylinder block reconditioning requires an automatic
honing machine to control size, surface finish, and crosshatch pattern of
the cylinder bores. A manually operated hone does not give satisfactory
results and is not recommended.
To facilitate reconditioning, pistons and rings are available .020 in.
(0.51 mm) and .040 in. (1.02 mm) oversize.
Connecting-rod and main bearings are available .010 in. (0.25 mm),
.020 in. (0.51 mm) and .050 in. (1.27 mm) undersize.
Main bearings are available with a .010 in. (0.25 mm) oversize
outside diameter. These bearings are for cylinder blocks that have had
the bore for the main bearings bored oversize.
