Could it be that my old spark plugs were ok, heat range wise, but the octane booster that was still in the tank when I first ran the motor turned them orange? And...now the new stock heat range plugs are too hot?

Well, I figured the car ran good all this time with the colder plugs so i put some tr6's on there. Gonna drive it a bit and see how they look. If it stil looks like theyre cold Ill put the champions back on. All I know is I shouldnt see any more rust colored deposits on it.

As I understand from chestry, no way. Nitro Methane does not mix with gasoline.
But Nitro propane does. It's a fantastic way to blow the holy fuck out of your engine!

How many quarts in a case? A 5 gallon pale (20 quarts) is about $250 last time I bought.

I think 16?
Better to run AV gas mix. Its about .90 a gallon, and is something around 130 octane. A 10/90 split would be perfect to considerably bump a tank of fuel.

I'd have to check my garage, but I think it's 8 (if it's the same I got years ago.) The beauty of Torco is small amounts bump the octane a fair bit. Like I said, I was getting about the same results from one quart as I was getting from nearly two gallons of Toluene.

I think white means too hot or coolant fouled??

Well guys heres what I found....first all the whitish color is from the plating on the tip. The nickel coating gives it that color. I hadnt seen that before with my autolites because they have a black coating, not nickel. What I did go off was the color band you can see on the ground strap. With the stock heat range they were close to the base, indicating it was on the hot side. With the ngk tr6's, the mark is now closer to the middle of the strap indicating a proper heat range. I noticed the car idles very well with the ngk's and seems to rev up smoother. Also less exhaust popping on decel. Only thing now is, I did a 3rd gear wot test on the fwy today while data logging. I figured it was warm and if I would see any detonation it would be then. I got no knock and the car felt great BUT the timing at wot was 31.9* when I had tuned it at 28*. Idk why it would jump like that. Would the ecu advance the timing? Or maybe a timing table is different if im manually in 3rd? (4L65E 4spd auto). Wierd.

AIR, the LS ECU will "trim" timing +-. Basically, it says something like, "mmm, no knock and not too lean? well then turn it up man!"
