Clear help on converting to a carb...
I've been searching around tonight and I couldn't really find anything super useful on converting to a carb setup (yes I know EFI is "better" but I'm looking to do something different because it's just intersting to me). What exactly do I need and how much should it run (where can I get it...and not the RB stuff or Mazdatrix, I'm looking for something cheaper otherwise I'd just buy a standalone anyway). I don't really care if it's used or takes a little work. Please help me quench my thirst...

I would think that this falls into the "if you have to ask, don't do it" catagory. Seriously, if you don't even know the basics, then conversion to carb will be a long and difficult process, resulting in a car that runs poorly.
But if you are hell-bent on going through with this, then talk to the 1st gen guys.

Converting to a carb is not that difficult, but it is a little involved.
You will need a new manifold, carb (of course), distributer from a first gen, 1 of 500 different coil setups (everybody thinks that their way is the best here), new fuel system.
I have had luck with off the shelf holley 600s sitting on top of RB manifolds. You can get a pretty cheap 600 off of ebay, but it takes a bit of time to get them dialed in. For the least amount of headaches though, I'd suggest just sucking it up and buying a kit from either racingbeat or rotaryshack.
For the fuel system you can either buy a low pressure carb pump (holley red or blue, carter etc...) and a deadhead regulator; or run the stock pump, a return style regulator, and a large return line to the tank to keep the pressure down. I have had success with both setups. Holleys like about 6 or 7 psi of fuel pressure, webers like about 3 or 4 psi.
Ignition is pretty easy. The most simple arrangement is copying a first gen ignition. 1st gen distributer, 2 blaster coils. Switched 12volt to coil positives and ignitor positives. Leading ignitor negative to leading coil negative, Trailing ignitor negative to trailing coil negative. Tach signal off of either coil's negative...done.
