Torque is 20 ft/lbs and gap is .45 I believe. I usually gap a little closer , like .35 because I spray nitrous. I'm surprised they use Autolite plugs, I run copper Champions and they last really well, got 80,000 miles on the ones in my RT Magnum wagon. NGK's have also worked well. Put a little Neversieze on the threads.
