I've been looking at running a plate system on my car. The Bottom end of the engine is stock, it's an 82 engine with head work, MP cam, MP header and a 600 holley. Should I use colder plugs, do I change my timing and will the stock fuel pump handle the fuel chores with the nitrous. I'd like to run a 75 or 100 shot.

Go 2 steps colder on plugs, back timing down about 5 degrees, run the best gas you can get, and the stock fuel pump might support a 75 shot IF you don't let the nitrous pressure get above 700 psi.

The more fuel pressure you run the more nitrous pressure you can have without burning anything up. High nitrous pressure with low fuel pressure means you'll be damn fast until it eats itself.
