Thanks Eric, I really appreciate your help. Now that I've given it some
thought, I think 22 lbs sort of makes sense. Since this engine doesn't have
main bearing "caps" like linline 4-cyls with cast iron block, it uses the
flat surface of the entire case halves to hold the main bearings in place.
So all the bolts, even the small ones, intrinsically keep everything in
place. So if you torque the main bearing nuts at like 65, and the little
ones at 15, it would probably warp the case or something like that. So I
guess I'll go with 22, although it still doesn't sound tight enough.

My Bentley states,  case halves: large 22 FT/lb,   small 15 ft/lb
  sound wrong to me also....  22 ft/lb is nothing...
