Just back from a week of hiking in the Smokies . . . hence the delay in responding.

The crank journals are huge in comparison to the saddles and caps:

Inliners post circa '14

Do you have the bearing shells handy? If so, see if the staking in the block and the cap are aligned by installing the shells without the crank. If the shell halves are aligned I'd venture to say it came from the factory that way.

It's really only the wrap-around thrust bearing shells that need to align perfectly centered front-to-back - which positions the crank. The rest of the journals then lay&run where they will. Have a look at my posting from '14 - in some cases the shells are much narrower than the saddle and cap. That said the front-middle cap of my 216 block is fairly well centered but by no means perfect.
