Correct Spark Plug &Gap
Was wondering the correct spark plug (Autolite) and gap.
72-340. Motor was bored .30 over has a 4 inch stroker and a 508 purple cam. Top end has Edelbrock preformer heads and a offenhauser intake.
Thanks.

Mopar motors like Champion plugs. I know, I know. You would think that it doesn't make that much difference, but it does. As far as gap goes, i'm not sure. A lot of it will depend on what you are running for an ignition.

the autolite plug you are looking for is (65) and the gap is 035. if its a "built" engine then i would use a cooler plug like (64) with the same gap. i my self use only autolite in everything i own,
