The Great Pumpkin - '71 Duster

So I've finally finished things up to the point where it was time to start the car up for the first time in over a year - NO DICE! It turns over but won't fire. I've been through everything but I can't seem to figure it out. There are so many deviations from stock at this point I'm kinda feeling a little lost.

Here's what I've done to troubleshoot so far;

• charged battery
• checked grounds
• verified distributor/cam timing about 5 times - correct
• verified MSD is working following troubleshooting procedure in manual - good
• checked voltage at MSD signal wire - good
• checked voltage at MSD power wire - good
• gapped spark plugs to .045"
• verified plug wire firing order - correct
• verified ignition switch wiring with FSM diagrams - good
• rebuilt carb due to leaking secondary bowl
• verified fuel getting to carb, good pressure, float levels set

I thought maybe the plugs were getting fouled so when I re-gapped them I cleaned them off but no change. They're probably fouled again from cranking without firing, probably need to go clean 'em off again.

There's old gas in the tank but it burns fine. It's a mix of pump 93 and Cam 2 100 octane unleaded. Does not smell bad or anything. I really don't think that's the issue. It's been pretty cold here so that may be a problem in itself.

It was also blowing fuses when the key was switched to the start position but it was because the alternator was powering up on the wrong circuit. I moved the wire to a different terminal in the fuse box and the fuses were good the next time I turned the key on.

So I'm out of ideas for the moment. Very frustrating but at least I've found these little issues and resolved those. Maybe someone can give me an idea.
