First off that water pump you had I dont think will work to well out on the street. It would be ok for strip duty but that would be about it. Get a CSI like this one.

I see them all the time on e-bay for sale for the big block mopars going for around 300 new. Besides that check out TTI for headers. Do yourself a favor and go with a 4150 Holley and stay away from the 3310. Its a good street carb but not great for strip work. As far as the ignition system goes the easiest way would be to just with a MSD 6AL and call it a day. Good luck and post up some pics man.
