BB plug recommendation - 05/27/08 11:27 PM

I'm currently have problems with a horrible miss in my 383 (see earlier post dies at 4500). Gonna start at the plugs and work my way back. I started pulling the plugs currently in the engine NGK Ridium Xrsix.
Can someone recommend another plug to me. something alittle more common. I just don't like the looks/design of the electrodes on these.

Thanks

Autolite 85's. Champions? Wouldn't even consider them.

champ RJ12YC i would agree with you on, but champ J12YC is a whole different ballgame.

The best plug we found for the wedge big blocks are the Autolite 85s..

I've run the champions for years, and now I'm trying out a set of NGK XR7's they seem a little smoother, but that's purely subjective. I beat the jeepers out of the last set of champions

, broke the enging in on them, then a cam swap, then over a thousand street miles and they were worn, but not fouled. I'd run either
