CNC-D,
my apologies for spreading erroneous information. the small and large journal bearings share the 0.842" length. however one book I have calls the 0.842" as HD for the sixes. and somewhere I have a book that indicates narrower V-8 bearings were used for LoPo apps.

I think I might be confusing the 151 Iron Duke rod bearings with 153 and thus 194-250 sixes. I must quit trying to remember everything and use the books I have for giving me the correct info. Mia Culpa.
