I'll add that the only thing I use instead of a torque wrench is a rod bolt stretch gauge. After using one, you'll never want to be without one. You go back to the torque wrench after you figure out what setting is required to get the stretch specified. For all other fasteners, I've always followed the mfgs specifications (typically ARP) for lube, torque steps and final torque. I've been fortunate to have done several engine builds, most for racing, and have never had a rotating assembly failure traceable to a fastener.
