nash content: the 234.8 had shell insert bearings starting in '33-4, but the straight 8 had babbitt bearings like an older nash six, according to egge machine. i wouldn't be surprised if both were derivatives of that '20s design.
Re Babbitted 8s - not by 1940 they did not. Couldn't have taken that much longer to change over. The 8 was still on paper for '42 but the number of 4280s produced must have been incredibly small if any.
The 1940 and earlier OHV 6 engine had much more in common with its forebears. Major revisions took place in 1941 and again in 1950. It's probably fair to say that the 1950-later engine (bumped up to 252 around that time) has a lot in common with the 232/258 for decades to come.
