Which plugs should I go with?
ACDelco Professional Platinum
ACDelco RAPIDFIRE Performance Platinum
Im going to treat myself this week. Im going to get some work done to the vette. Im ordering 2600 stall,Lt4 1.6 RR, Hooker headers, magnaflow spiral cats, MSD wires, and plugs while I got the manifolds off. Toys to feed the need for now. Here I come Credit card lol
Well I decided Im going with shortie headers for now. Ill upgrade after deployment and the state inspection to LongTubes. After deployment the engine will be pulled to become a 396.

I dunno about the LT1, but my L98 absolutely hates the fancy plugs. It fowls them all up in a few days. I am running cheap champion plugs and it couldn't be happier.
Just something to think about before you dump money into expensive plugs. Not all engines will benefit from them depending how they are tuned or designed to run.

I have always run the AC Rapidfires in my L98. I ran them in my 87 years ago and it ran great. I just put some in my 85 and it runs strong. I like them
