YOUNG GUN: Putting Nitrous on 318!!!

Well about a week before I hooked up the nitrous I bumped the timing up to 14 initial and 36 total just to see how the car reacted and it ran good. So I figured backing it down to 10 (4* change, 2 per 50hp) would be sufficient with the nitrous. Like I said I pulled the plugs before I ran the nitrous to read them and get an idea of what was goin on in there. Didn't appear to be too rich or lean, the plug temp appeared to be a little cold, and the timing line was just past the 90* point on the ground strap so maybe just a lil too far advanced. Gonna run it a few more times and pull em out again. I'm definitely being cautious cuz me of all people don't want this to be another " I blew my motor up with nitrous" threads.
