A healthy 408 should have TR6's on motor and should get colder as you spray more N20.

I would use a TR8 for a 200 shot.

My 396 and 400 shot we use TR11's

I would drive it on 6's or 7's and spray it on 8's or 9's at a minimum. guys around here are afraid of 10's and 11's but we use them regularly.

I would be on a 8 at least. Let me know if you need any part numbers.

They would be fine if your tune is good. they will foul faster if your using leaded fuel then let the car sit alot. We can run all day pull it in and out of the trailor on a set of 11's buit if we let it idle then let the car sit for a week or 2 the plugs will be ****.

Plugs are cheep change them often. get you a set of 7's drive on them then just chanfge them when your gona spray.
