I just ordered the McCarville tune up kit for my 91GT's long-overdue tune-up... and I'm embarrassed to say it, but I can't remember what I should gap the plugs to! I'm running a bone stock motor- I do, however, have the Crane PS-91 coil, which would lead me to believe I can open up that gap a little more. What do you guys recommend?
