Jermey, the factory assembled SHO motors have rod to jounral clearances much closer to the low end of the spec, thus the initial bearings last awhile. My issue is with the Clevite bearings that are typically Plastigauging out to 0.002 which is at the extreme high end of the spec. You need DOUBLE the volume of oil to keep this high end of the spec floated hydrodynamically, as compared to the low end of the spec. Then think about the higher volume oil pump Ford switched to for the 3.2. Wonder why they did that?
I see what you mean about needing more oil to fill the void. I cant remember what my clearances turned out to be when rebuilt my 3.2. I think they were about middle of the road. I had all my rods checked and refurbed. Not sure if that effected clearances at all.
