What plugs are you guys running on your 57 Fury 318 engines
and 58 Fury 350 engines? The original factory manual stated they took the same
plug, AR32, but now the Autolite website says that the 57 318 takes a #85 and
the 58 350 takes a #86!
Why were they the same when they were made, but now one takes
a hotter plug than the other?
I appreciate any informed opinions.
