you said your gas is reddish, it could be old farm gas, i drained some out of a 71 and it came out reddish in color, plus it smelled pretty bad, didnt smell like regular gas (which smells good) but dont remember if it was sweet. i dont really like the smell of antifreeze either so it might have smelt sweet. but i never saw that truck run so i couldnt tell you about the exhaust color. i know when its cold out my truck leaves a smoke screen behind it, even when it has warmed up, and im talking plooms of smoke. if i were u i would check your coolant level, run the engine a while, then check your level after it has cooled down.
