340 not running anymore...Help Please?

Hey Guys,

I'm hoping I might be able to pick y'alls brains...My car isn't starting and I'm at a loss here.... Here's the history I have on it
I bought a 72 340 Demon back in November. I had to redo the front suspension, which took me a little longer than it probably should have, so it sat for a while.
Anyway, when I got the suspension stuff fixed I took it for an alignment and wound up having it overheat on the way to the alignment shop. My fault, I didn't properly refill the coolant.
Overheating didn't seem to do any damage and I drove it fine for the next few days till I took a spin in the snow, bent rim...... sat for about a week till I could get that fixed. Then ran fine for a few days, wheel fell off..... twice... and again sat for a couple of weeks till I could fix it with new longer wheel studs and lug nuts that would correctly hold the Centerline rims. I also did an oil change at that time.
Ok, so it ran fine after that till the passenger side ball joint popped out of the control arm. It sat, I fixed and then this time it wouldn't run.
It started ok, but didn't sound right to me, then slowly bogged down over the next minute or 2 and stalled. After that it wouldn't start again. I pulled the plugs and they were oil fouled so I replaced them with new champion plugs. Same thing as the last time, started fine, sounded not quite right, bogged, stalled and wouldn't restart. Pulled plugs, oil fouled.
Considering that it had sat as much as it had I thought maybe the valve guide seals so I replaced them and they were definitely no good, small tears throughout. I cleaned the plugs up and tried again. It started, sounded no better, bogged, stalled, and again wouldn't start. This time when I pulled the plugs they were gas fouled. Now I'm stuck... Too many possibilities and I'm not sure what route to take.

Sorry about the huge back-story, but I wanted to give all the info I could.
So, any ideas? Thanks in advance
Angel
