I would do 8's or 9's.. I like a colder plug then some of the other people on here though. We run 10's in WhiteLTone's car shooting 250.

I believe a #7 would work great for you.

he has an n/a tune in it now. should i pull 2 degrees per every 50 and the work from there? i haven't been able to find out how much timing the tuner left the car at.

I would pull 8 degrees to start and work your way up. Better to start with too little timing than too much especially if you don't know what the timing is currently. I would also run a #8 plug.

I'd probably start with a smaller shot like 100 hp at first.

I started out with 51n jet tune and pulled 7 degrees. After a few test passes, the plugs looked great, so I bumped it to a 55n jet (125hp) and left the timing at -7 degrees. The plugs still look great. A light fuel shadow and a timing mark just above the anode.

Next I will go 59 jet and see how that looks. Then I will go to the 63n jet tune (150 HP). Overly careful? Maybe. But I think I got some great, safe results.
