no, it is smaller diameter crank main & rod journals

it was done at the factory to use crankshafts that didn't machine with the desired surface finish at STANDARD OD size

piston bores & lifter bores can be oversize on a factory block, because once the material is removed - larger is the cheapest way to go for a "fix"

block main/caps & rod/caps (because there are two halves) can be machined & returned to the STANDARD ID
