Plug gap for a 200 shot I have a 408 with a direct port 200 shot on a stand alone with 116 fuel. Running TR6's. If I go to track may go to a BR7. What is a good gap for plugs. I am thinking .35 can't remember and search is no help.

10.5 compression. I pulled plugs and they looked good. No detonation and don't really seem to be to hot on 6's according to the ground strap. Running a little rich though.

When you lean it out its gonna get hot FAST.
Why do guys even bother asking if your just gonna be like "they looked good"
Post a pic, I bet they dont look that good.
A good running 408 needs a tr6 with no nitrous. 200 shot you should start 2 steps colder. Good luck, hope you dont melt it before you figure it out.

I tried to get a pic smartass. They don't turn out good. The pocelain is glowing white in them or to dark to tell anything. Crappy camera or crappy operator I reckon. All this thread was asking for was the recommended gap not for people to be a wise ***. And yes hopefully I will get it figured out.
I'm just trying to give you some helpful advice from someone who has a few pistons for ashtrays.
Its the wrong plug no matter how it looks.
BTW .. what did it run?

Thank You. Set gaps to .30. When I go to the track i will put either 7's or 8's in it as I said at first of this thread. Don't plan on spraying on the street, can't hook on street tires. I pull 8 degrees out on spray. 24 total in it and 18 on spray. A/F on a wideband and on Dyno runs 12-12.5 at either wot and on spray.

24-18 is not 8..... but 18 is pretty good and 12.5 is a good starting point. Ill think you willl get to 20 on the timming and closer to 12.5-12.7 when its perfect. seems like what the nitrous ls1's want. BTW we run a ngk10 on the 200 and 11 on more juice on our 396 with 116 gas.....

Sorry my bad 26 total degrees. 8 taken out. it was on a dynojet. This is a full weight street driven 02 RCSB truck. I only sprayed it one time on track and 3 on the dyno. Fairly new to nitrous as you can tell. LOL. It got 12.6 @ 107 or 108 on motor with a 1.8 60'. I didn't get into the spray til about 100' to 150' out and got 12.3 @ 116. I don't plan on spraying it anymore till I get the suspension figured out. Can't come off the line hard. it bottoms out and rebounds and breaks loose I think and from what some of my friends were seeing. Still got a ways to go but slowly getting it figured out.
