I would like to hear from you. What spark plugs are you using in your stock 440. I have a stock '68 R/T, 4 spd.  Just trying to get some ideas of what has worked best for you.

Bone stock, i would just run the standard autolite coppercore. I ran them in my street strip 383 into the low 12s without a problem.
