Spark plugs... Just looking for a sanity check, according to the sticky...
Engine: 346 11 degree heads CR: ~12.x:1
Says I should run 9 heat series for motor alone, 11 for a 200 shot and 12s for a 300 shot. Does this sound right? Sounds too cold to me. Motor should make mid 8s on nitrous.

Phil,
You're right, that is too cold. I don't think you'd ever get the car to idle on an 11. 9's will usually do the trick on a 300 shot, just don't get a projecting tip.
