first of all, you have a massive cam. that thing is way too big for those gears and converter...it's gonna fall flat on its face until 4000 rpm, so you either need 4.10s and a 4000 stall or what i would go with is 4.30's with a 3500 stall. less wheel spin because of the converter and less slippage at higher rpm.
your intake and carburetor setup seem alright, but i fear you might be a little small on the carburetor. i run a 750 on my 360, and it seems just right, maybe an 800 would be ideal for your situation, but try the 750 out just to make sure. going smaller is always better than too big on a carburetor.
your probably gonna make max power at around 6000 rpm. this mostly depends on what you have done to the heads, but everything else sounds pretty wicked so i would say 525 hp wouldn't be over estimating with a motor that done up. with the nitrous you can probably expect about 100 hp extra unless you have a nitrous cam, than your n/a hp would be down by about 30 but you would pull the full 125 horse out of the nitrous.
what kinda compression do you got? you need at least 9.5:1 if you wanna live with it on the street, 12:1 or more if its a race only machine.
i would expect mid to high elevens on the motor, maybe high tens on the nitrous but probably not, more than likely low low elevens when everything is said and done.
i would go with a high volume oil pump. if my guesses are anywhere near correct your still gonna spin the engine in excess of 6500 rpm and your gonna need the oil to be there all the way to 7000 in case you have to play catch up at the race track.
and lastly, i run ngk v-power plugs in all of my cars. they work really well all the way to 7000 and they don't foul up as often as the bosch platinums that i ran for a season.
let me know how close my estimates are once you get it to the track
