point 70 mm (2.75 in) from top of each cylinder
bore:
Cylinder bore diameter =84.460 to 84.442 mm
(3.325 to 3.324 in)
CAUTION: Measurement must be taken
from side to side and front to rear of bore:
CAUTION: Cylinder bore diameter and
ovality must be within limits given above,
no reboring, honing or glaze busting of
