Spark Pluges

[Mango]

Hey All

What pluges do you use in a small block 350 with high miles?

We used AC in all our squares (3 GMC pickups and 5 Burbs, GMC and Chevy)+ all 3 of my OBS trucks. I think Dad put AC in every GM vehicle we had. I just replaced the original plugs in my crew cab a few months ago; it had AC iridiums in it so that's what I put in. They're more $$ but they last longer. Got 130K out of the original ones, and got 95K out of a set of regular AC plugs on my '90 Burb. Still looked pretty clean when I pulled them too.
