Where can I find bolt torque specs? Currently need specs for bolts holding exhaust manifolds to head. |

They're 1/4 inch, no more then 3 foot lbs. RR never did post torque specs, not even for the nuts on the studs for the engine head. In this case, I just snugged mine up by feel. You would be hard pressed to get anything in there other then an open end wrench, so a torque wrench would be rather useless. Keep in mind too, that the threads are worn on both the studs and the brass nuts, so even at 3 pounds, you may strip out your brass nuts. That's where doing this by feel is better, you can't feel a nut letting go with a big clunky torque wrench on there, even a small one that uses inch pounds. I made all new studs on my car out of stainless steel, the one end in the block is BSF and the other I went with standard 1/4 28. This allowed me to use stainless nuts. I made the car look stock by making steel sleeves to mimic the brass RR nuts. Also, the studs are threaded into the block, not the engine head. |
