Hi there....can I get a little help. What do you guys think about the spark plugs.

Fuel, 91 octane, pump gas.
Engine, 472 Hemi, 11 to 1 compression, aluminum heads,
Plugs, Autolite 63.
Timing, total is 30 degree.

What do you think??

Thanks, Troy

....there is nothing like driving my 1968 Hemi Dart around town and having people looking at you like you're nuts!!
