Default Conrod spec for floating bearings/ finish

Just a quick one guys the torque spec for a 37 engine with floating flanged bearings [pretty sure it 40 lbs of the top of my head] Also the type of finish that should be on the rods after sizing for that type of bearing>?

For torq specs Van Pelts has them all for you...have to love that he is letting us use him as quick reference !
Bearing surface...an old crankshaft is about 15Ra a modern is about 10Ra or better.
Anything 10Ra or better is considered a mirrorfinish...which i think was the quite vague reference i´ve seen in fords remanufacturing specs.
Honing for mirrorfinish is slow...not something a machineshop love.

The conrod size is 2.220 I have it honed to 2,221 with the fine stone,Not sure what grit it is,but it sure does shine them up.
Good info.
