It's .035" for the plug gap (up to 1996). 1997 and newer use .040".
On the LHS...it depends on the engine (3.3L or 3.5L).
3.3L = .048" - .053" (.050" is average)
3.5L = .033" - .038" (.035" is average)

To Josh and Ray: Thank you, that's the answer I
expected. But does anyone have experience run-
ing a GenII through a Calif. Smog CheckII test at
.040. Thats the one using the dyno. I ask this be-cause Chilton says .050
for 3.9's 1995 and up. While Fram says .035 up to 1996 Then .040 for 1997
up. Do you see my point? I don't see any difference between 1995 and 1997
ignition sys- tems, so is .040 really a better gap for ALL magnums? Now if
someone could only tell me what the proper gap is for a '94 LHS. Same BS
there. .050 on the sticker, .035 for a AP985, and now .035 for a Champion.
By the way, the old wires ran at about 5000 ohms but I put new ones on
anyway. Thanks Biff
