Duration on the cam is? That is very key here since you plan on running N2O. Also the LSA (Lobe Seperation Angle) on the cam is also key for N2O. You may want to read up on fuels as well (

The last thing you want is detonation, so I would not turn on the nitrous until you have some good fuels in the car. For example, I have 12.4 to 1 C/R and run VP Racing fuel C16. At $7.50 per gallon nitrous can begin to cost a lot. To save some money I bought my own refill station and now have about 10 bottles. I get about 4 passes out of 1 bottle @ 150 horse shot. I think you will be changing out your bottle every 2 passes @ a 350 horse shot.
Just some things to look at and think about.
