Next retarded question

Ok, here's the next one. This is a little more immediate than the supercharger, which is going on next year.

A buddy of mine with a 67 pickup and I have been exchanging smack talk for the last few years while we work on our cars. We're finally about done with them, and we're going to finally see who is faster this year at the track.

I dont like to lose, and I'm certainly not going to lose to a chevy without a fight. I just picked up this setup on ebay, and I already have a bottle. What else will I need to get to have a working nitrous setup on my Duster?

FOr what its work, my car has the following mods -

318 motor, healthy
unknown comp cam
headers, dual exhaust
M1 manifold
3.91 gears
625CFM carb
FBO "whole shebang" ignition

My buddy has a 400 small block, headers, RV cam and 650 CFM carb. After I race him I get to race his brother (who REALLY talks ****) with a stock LT1 camaro. Heh...
