You have alot of compression @14.1 for nitrous and the cam is a little late on EVO.... but it should stand 300-400 depending on how good your tune up is and what fuel you run.

Alot also depends on how much quench distance the engine has, ring type and gap, and if the heads are the old SVO bathtub chamber or the newer double quench pad fast burn chamber.

I take it your going to run a fogger? 28-35 jet?

I would recomend VP NO2, C23 or Sunnoco MAXNOS for fuel.

Make sure you have a dedicated Holley 803 fuel pressure regultor for the nitrous fuel side, so you can set your flowing fuel pressure.

Plugs should be NGK -10's.

On 300ish (28 jet) I'd start with 18* total timing.

That motor should make 950-1,000hp on motor if the cyl heads are any good.

in EZ Street 14:1 CR with a 500 shot was the norm. slightest screwup on the tune meant white smoke at 1000 ft. Nitrous is an art, the tune done by the artist. PM me and I can put you in touch with an excellent nitrous tuner. You will need a different cam though. Lobe separation is not fit for the job.
