    torque

    head torque
    not sure where this post came from...try a search for torque--------------------------------------------------------------------------------

    I have gotten different answers for this question.
    BAE says: 9/16"=145lbs, 1/2"=120-125lbs
    1. KB says: 9/16"=120lbs, 1/2"=85-95lbs
    My ARP catalog says: 9/16"=122lbs, 1/2"=84lbs using ARP moly. OR using 30wt oil for lube 9/16"=159lbs, 1/2"=108lbs.

    I guess this gives us a "range" to work with.
