I've got BKR6E NGK's and they seem a bit too cold to run on the street. I've used a 5 heat range at the track with my iron heads and melted the tips on two cyl.

I used to run Champions in my 340 back in the '80s and they had so much resistance the spark would arc out of the plug boot and to the head. Spent a long time swapping in new plugs, new wires, new everything. As soon as I stopped using Champions and went to Autolites problem went away. I will NEVER use Champion junk again.

For a street car, I would try a -7 or -8�I have had issues with fouling -8�s when my car was a little rich, but they worked well on the bottle. I used -7's for everyday driving. 67 Barracuda street car, 408, e85, 1.38 60', 6.44 @105.9 in the 1/8 mile, 10.19 @130.5 in the 1/4...so far....
