What Plugs do you run?
For my 68, I am running tr55 plugs, Silverado CAI, 3" exhaust out through Magnaflow mufflers, Howell Harness and tune.
For the SS, I have no idea what plugs (same from when I bought it), SLP lid, Magnaflow cats, fake flowmaster, CME, and !AIR next week.

I have them in my DD, and for my LS1. I noticed my DD running better after installing them. I think they are like 6 buck a plug.
