Need cam selection advice

Like the title says I need help selecting a cam. Here's what I have, or will have in the very near future. Car will be an 80/20 street/strip car. Mostly for blowing away the rice-heads, slomaros, and thoses annoying 5.0 cars

D1VE block .060 over
D0OE-R decked an unknown amount
Eagle cast steel crank stock stroke
Eagle ESP H-beam forged rods
Pistons are 12.1cc dished and should net around 11.1:1 CR
Intake is a Weiand Stealth
Carb is a BG 750 Speed Demon (yea, I know it's too small but my pockets are only so deep at the moment)
I also have a 2-stage nitrous that I was going put a total of 100-150hp shot just for special occasions
Trans is a C-6 and is SUPPOSED to have a 3500 stall in it.
Rear gear is currently a 4.10, but I will be dropping to a 3.73 for a little less RPM's on the street.

Car currently has a CompCAms TRUCK cam in it at the moment. I really need some idea on where I should be at with lift and duration. I read somewhere else that nitrous likes a longer duration. 290-310 ????? Can I get away with a .590-625 lift??? Any help in this would be greatly appreciated. I posted on the other place, but didn't seem to get much response.

why the stock stroke eagle crank?

I picked up a killer deal on the rods, pistons, bearings and ARP stud kit. $450, I couldn't pass up because I got it broke off in my a$$ when I bought the motor which was already supposed to be built good. I'm just trying to make some horsepower on a budget. Right now I couldn't even sell the car for what I have in it, unless you want an over-heating POS with 5lbs of oil pressure.

no more than you plan to spray i would'nt worry about a nos cam.is your car a fox mustang?just guessing.
