Wheel torque specs are found in the AIM and GM Chassis service manual and are based on the size of the stud, in our case 7/16 x 20. '73 GM Chassis service manual calls for 75 ft lbs.

I've been doing my wheels at 90 lbs for the past 9 years with no problems.

Steve's post about the stud determining the torque spec makes more sense to me. Do you really want to risk snapping the stud or stripping the thread??? I'd go with 75 and check them frequently for a while.

Torque spec for a C5 are higher because they used a different stud. A 7/16 stud bolt is not designed for 100 ft lbs of torque. If you call a wheel manufacturer they will tell you to use the vehicle specs unless you've changed the studs.

Steve is correct on this,75 ft lbs, i recommend as well,seen quite a few C3's with broken studs over the years,when over torqued they fatigue and eventually break.
