I would get rid of the Autolites for one, a set of Denso Iridium go one step colder then what yourr stock plugs are. As for your timing, back it off two degrees. You might have to play with the timing, as for the gap no more then 45 degrees and don't forget one step colder. When you tune this, make sure you do it on a dyno for full potential and no unsuspected popping from anywhere, Mike. SCT Tuner.:bigthumbsup P.S. As for the Densos, they may be costly but well worth the money. I know a few friends of mine, that are on their second and third season with no problems. My own is on it's third season, and consistant 1.09 60 ft times at 7.973 at 183.897mph. Mike.
