Looking for some good info.. Trying to figure out the best plug for my setup. Here is what I got, Basically a stock bottom 5.0, stock forged pistons, and up graded ARP bolts, and studs, set of TFS Tw heads, 1.6 RR, Lunaiti ??501014, Vortech s-trim 8lb pulley, but going to have high trac. 2.95 or 3, 93 cobra intake(ported & polished), 42's, 80 c&L, 70mm TB, shorties, off x-pipe, 2 chamber flows.

I thinking of Autolites 3932 ??? and I think 3934's are stock range

need info. on NGKS, DENSO, and maybe IRRIDIUM plugs
