I have an old Federal-Mogul bearing manual that has the following info:
201.3 cu. in 6, 34-41, crankshaft forging no. 612456, 4 3/8 stroke
Diameter of standard crankshaft
Connecting rod (all) 1.9365/1.9375
Main #1,2,3,4 - 2.2490/2.2500
Oil clearance - .0007/.0027
The Fed-Mogul bearing numbers are:
Con rods - 9075SB
Main #1 - 9076SB
Main #2,3- 9077SB
Main #4 - 9078SA Flanged
Not sure if this was everything you needed, but hopefully helpful. Good luck.
