NGK TR55's unless you plan on nitrous the go with the TR6's. SPEED INC, which is a sponsor, is where I got mine.

Nice Caddy BTW. Lovin that hood.

I am trying something different in my 427. I am trying the new Autolite Xtreme Plugs. They have a cut back electrode that exposes more spark, designed kind of like the AC Rapid fire plugs.

The part number I am using is: XP5245. So far so good. I only have 15 miles on the motor, so we will see!
