This is probably pretty dumb but I need the Spark Plug gap for an AMC 360 V8. I was told by an autozone that it was .035 but the plugs came out between .025-.027 and a google search went as far as recommending .050-.055. Thanks in advance.


Fred as a general rule .035 gap would be good for a carbed engine.. However it has been found the gap needs to be increased to .045 or better in fuelies.. The reason is the fuelies have such a LEAN mixture that sometimes there isn't enough fuel in a .035 gap to ignite when the spark occurs.
So if it is a carbed engine ONE gap and a fuelie ANOTHER gap!
BUT there is no reason to install a high energy coil into a carbed engine and open the gap..There CANNOT be a gain, ever!! No matter what the armchair mechanics claim...NEVER is there a gain!!
