'86 sport coupe motor build up...what you think??

Here's my plan for my '86 sport coupe...i'd really like to do a blown set up not even as radical as my Z but i can't afford that route right now. Tell me what you think of this combo:

350 4 bolt main bored .030 over
steel crank, rods and forged speed pro pistons, 9:8:1 static comp.
edelbrock perf. rpm alum. heads 170cc/70cc, 2.02/1.60
edelbrock air-gap dual plane manifold with 750 holley DP
crane cams hyd. flat-tappet 218/228 dur. @.050 and .454in/.480ex @ .050
NX hitman nitrous kit (150 shot)
edelbrock victor series mech. pump (130gph along with a small holley 45gph booster pump near the tank).
aeromotive boost ref. return style fpr.

I know the cam is kinda conservative but I want it to be civilized on the street where it will spend most of its time as we only get a short track season out here. Any horsepower guesstimates on and off the juice??

looks to be within reason. should do about 380 without the nitrous and 500 area on the juice.

And never again driven on the street.

How do you intend to get this past Envirotest?

Stroke it and get some better heads. If you're going to buy a roating assembly anyway, might as well go the 383 route.
