F-12 engine bolt torques

[Senator]

Finished engine teardown yesterday on the 1936 F-12 I recently acquired. Block and head are off the the machine shop for clean-up and valve job. Started thinking about putting things back together last night. I have a reprint of the service manual, but nowhere does it have bolt torque numbers. Looking for numbers for mains, rod bolts, and head bolts. Anyone help me out?

 

[Dave Allgire]

I've torqued the mains at 75 ft. lb., rods at 45, the head at 90 ft. lb. You might have to make some minor adjustments on the rod bolts to get the castle nuts to line up with the cotter pin hole.

That's because there never were any torque numbers, is what the consensus was a few years back. The numbers Dave provided are good to go.

I have the same torque values except for the head, I have 65-70 ft lbs.
Do not remember the stud size, maybe the same size as a H and calls for 73 ft lbs. If I remember right these torques came from books the machine shop had.
