The Hudson straight 8 engines were all 258 cid. The straight sixes were 232, 262, and 308 cid. and highly interchangable. The little Jet engines were 212 cid flat-sixes.
For some unkown reason, the Hudson straight 8 never used an insert bearing. They were all babbit till the end of production. Nice little aside to those engines was a roller lifter arrangement as standard. Ironic that engine should be so far ahead in one respect yet so far behind in another.
The 258-8 and the 212-6 shared alot of common mechanical characteristics as they were the original family of engines produced by Hudson that dated all the way back to the 1920's. The Jet engine was updated by the incorporation of the insert bearings when the design was revived for the production of the little Jet.
Since Hudson and Nash combined to form AMC, then Chrysler snapped up AMC - I suppose a little Hudson automotive trivia is appropriate for the Mopar board, don't ya think? Its all in the family now anyway.
