need help Bad-excuse me for being stupid

Nothing wrong with Autolite plugs. In fact, I won't use anything else....in anything I own that uses spark plugs.
My 440 had Autolite 85's in it when I bought it. The car wouldn't run for squat, and would constantly stall. I replaced them with 86's, and it's been running like a scalded moose for almost 4 years now.
One other thing -- Autolite 86's are the same plug used in a '69 350 horse Vette. Just an FYI I know it really makes no difference, but just thought I'd give an example.

Bottom line, I think the 85 is too cold for your application, and I recommend replacing them with 86's.
