Default Bolt torque?

All the "long" main bolts (10) get 70# (with oil) and the "short" outers (6) get 65#.

Thanks, Gary in N.Y.

P.S. This is G.M.'s recommended numbers using their fasteners!

The long bolts on either the 2 or 4 bolt caps are 70ft/lbs. The rear cap, with 2 bolts is still 70ft/lbs. Short bolts on the 4 bolt caps, IIRC, is 65ft/lbs.
