Let me tell you from experience that Ford calls for .052 on the 5.0 HO motor. I recently did "green94droptop"'s plug, cap/rotor, and wires. He was gapped at .080!!! He just got the car so the previous owner must have been a _jackass. But he told me before I did the plug change that his car had bad throttle response and seemed like it missfired at idle. Now, those problems are gone.
