Thanks guys. I wound up looking it up in my 70 GTO factory assy manual. Since these are the (I believe) original bolts I torqued them to roughly the midpoint of the torque range spec...50 ft/lbs.

don't know what that number is...never even thought of looking. just a good tight with a nylock nut.

What are the torque specs for a 400 Pontiac engine mount?
Getting ready to install my new Pontiac build into my 70 GTO and I can't find the torque specs for the engine mount to frame bolts. These are the long 5" bolts with 7/16 X14 thread. Anyone have that spec handy?
