Ya know the MM isn't the ONLY engine Ford makes. I have been doing Fords and GM since the '60's and they didn't have the MM then.

I dont get an answer or I get an "I dont know, let me get back to you".
However I believe the factory recommends SAE 30 on things like rod bolts. Torque it 3 times and that will put you real close. Of couse every bolt stretches differently.
Whenever the T2Y bolts have the fiber or nylon or whatever on them heres what I read:
http://www.engineparts.com/motorhead...iles/frame.htm
Friction Loss: 90% of the applied torque to a typical threaded joint is used to overcome friction
50% of the friction is between the threads of the fastener & threads in the block
50% is between the underside of head of the fastener and work
10% of applied torque actually stretches the fastener, applying force needed to load the joint
Thats alot of difference!
