Well, proper to some may not be so proper to others .. :D
The "proper" way is to tighten the adjustment stud to 72 inch lbs, and back off from there. Generally, the front band is 2.5 turns backed off from 72 inch lbs, and the rear band is backed off 2 turns. A special tool is required to adapt to your torque wrench. If you need the special tool to do this PM me, e-mail or call for info.
You may get conflicting opinions on how many turns to back off with each ratio lever, etc from various builders. No two people build an engine the same, and no two people build a transmission the same. Do what works best for you.
The not so proper way is to "snung" the adjustment stud with a short wrench, and back off from there. Some people have a torque wrench built into their forearms. :mrgreen:
