You should be able to just to test the starter. I would  use some kind of a bump switch if it was me just for your safety and the safety of the engine. I've also got a 68' 428 its in my grand prix. Post some pics when you can and keep us posted.

First thing is to make sure that all the battery connections are clean and tight and has a good ground....If all that checks OK then check the connections at the starter solenoid...Look for bad or corroded connections broken wires ETC.. Use a 12 volt test light to verify that you actually have power to the solenoid....should have 12 volts on the main battery terminal on the solenoid all the time....if you have power there then take the test light and ground it to the engine block... Place the other end on the solenoid terminal with the small wires (the S terminal)...have someone turn the key to start the engine if it lights up that means that the switch is functioning correctly....If it does not light up that means the the problem could be the ignition switch itself...Next thing is to put the test light across both the small poles (on the solenoid) have someone try to start the engine again... the light should come on...If it doesn't that indicates a bad solenoid....if all that checks OK.....Then the issue is probably the starter motor....Since it has been sitting for years...the brushes might be sticking..If that is the case sometimes you can take a hammer and lightly tap on the starter to see if they free up...(Will probably be full of corrosion) then try to start again....(Try it a few times) If that doesn't work you will have to remove the starter and either replace it or disassemble it and repair It....(is a repairable/rebuildable unit).......

If you do get the engine to roll over....Would highly suggest that you take the fuel line from the tank to the inlet on the fuel pump loose and run a short hose from a seperate clean container with fresh gas to the inlet of the fuel pump so when it does start you don't suck 30 years worth of crap from the gas tank into the carburetor.......

Great goal bro. Cant wait to hear what kinda numbers she runs. What kind of upgrades are you think about to hit 12s. I'm gonna run mine down the track also just to see what she'll do and I've got a trip to the dyno planed as soon as I get the new tires and rims. I don't trust mine to go around the block lol.
