Smoke Blurred Visions
Well, in the painful saga that is the life of my truck, we have yet another strange problem. I went out and started my 1969 F-250, and after awhile, when it was getting warm...
SMOKE (maybe exhaust, regardless, it was quickly choking the life out of me) started pouring in the cab from the heater vents. The two on the dash, and the two down low. Why is this happening? Do I have something hooked up completely wrong somewhere? Any ideas would be appreciated, since I cant drive it as-is.

From the vents part makes me think that you might have a hole in your heater core. It's a little radiator that generates the heat the fan blows out. It is filled with engine coolant, and if it's hot it can make steam....should leave a sticky-ish film on the inside of the glass and smell sorta Anti-freeze-like or sorta like maple syrup.
If that is not the case, it could be oil from the engine dripping onto hot exhaust parts, as that smoke will work through the dash and come inside too....that smoke will smell oily or like burning oil.

Tristin, I think if it had been a fire, shutting the engine off wouldn't put it out, or it would smoke for a while after being shut down.
I also think antifreeze would make a sweet pungent smell. Burning rubber, oil and other items have a distint different smell.
Is there any evidence of water or stains in the passenger side floor under the dash?
If you feel comfortable doing it, try starting the truck again, have a garden hose (tested) close by to see what happens again. Leave both doors open so you don't fill the cab with smoke.
If you pull both hoses off the heater core at the firewall and insert a piece of 1/2" water pipe in the ends you can make a closed test loop to elimenate the heater core. You will need to clamp the pipe so that it doesn't leak.
Hope you find the cause.

Oh...never thought of that....and should have....as I just smoked a wire to my electric fuel pump the other day and had to replace the whole thing....Electrical burns/fires have yet another unique smell all their own.
