Big power w/ nitrous...get the MSD grid system if you can afford it. If you need a little more of a budget friendly option, get the MSD 6AL-2 programmable (6530). That's what I did.
For distributors I like the MSD pro billets, locked out, and use a crank trigger.

I also strongly recommend the Leash nitrous controller and their wiring board. Great working simple setup.
