454 + .040, 781 heads with large valves, 10-1 CR, 60204 Voodoo cam, Performer RPM intake, 770 SA Holley carb, 3000 stall, 4.11 gears, street driven

What would be the best choice in plug part numbers?

x2. The Autolite is a better plug than either the NGK or the Delco. I had a friend that was knocking the tips off of NGK's in his 17-1 compression race bike. A racing companion told him to go to Autolites and he didn't have any more plug related issues. If you use nitrous never use extended tip plugs.

I have good luck with AC Delco's and NGK's also. :D
