The '73 401 I just crated last night came from a Travelall. It had a
counterbore in the back of the crank that was more than big enough for an IH
pilot bearing. In fact it is prolly bigger than the pilot bearing for an IH
5 speed.

The bell bolt pattern is AMC and not IH. Instead of the bellhousing mounts,
the AMC-in-IH installs used mounts on the side of the engine block with a
'single point' tranny mount.

The clutch setup may explain(in part) why the 401 was 'auto only' in the
'73's, since the '74 changed from linkage to cable actuated clutch. I say
'in part' because there was already a clutch setup for the 232/258.
