Would anyone know the torque value for the flywheel bolts to crankshaft on a 1937 "120"? The bolt size is 7/16-20 and have the grade "B2" stamped on them. I've looked in the shop manual with no luck. I've also looked at torque tables on an internet search but believe it or not I've seen different values?

An almost identical 282 engine that is in your 120 was used thru the 47 21st series production so I believe this chart from the 46-50 service manual should also be applicable to your engine. It has the torque for the 7/16 flywheel bolt at 55-60 ft/lbs.
