Re: which spark plugs

I don't know, but for somebody to tell you you're probably going to have to tell more about your engine. Stock? Nitrous? Compression?

Also I've been told that iridium/rare metal plugs are not really better than copper in anyway except they have to be replaced less often, so if you can justify that expense...

Re: which spark plugs

Spark gap is 0.060 in.

I use AC Delco plug. Havent had much luck with Bosch, Champion or NGK over the years in GM engines.

Interesting! Makes sense when NGK is recommended for spray with these engines.

That is correct, last summer I went to the AC Delco parts store and bought some plugs. I took it out of the box and it's NGK Iridiums.
