Peter gets the gold star on this one. and to go one step farther when racing way back when we use to install cool cans. we ran our fuel lines thru them and would fill the can with dry ice. condenses the fuel molecules. combining cold air and cool fuel you can pack more into the cylinder.

and those canvas bags well they were for drinking water or could be used in the radiator. the air passing thru worked on evaporation to keep the water cool. [when i was a kid my dad always had 1 or 2 on when we crossed the desert to vegas or phoenix. man it sucks getting old]

your car if from the denver area should have been jetted out to run in the thinner air. [your car might be able to tune in the fuel / air ratio] just like when i took the 68 road runner up to reno and it bogged out something fierce. ran way too rich. just a big black cloud of gas belched out. back then carter carbs sucked had to take the top off to re jet unlike the holleys.

the symptom you might be experiencing is that fuel / air mixture is too rich and as the air condenses it's catching up with the fuel increasing the air mixture to fuel so the engine runs a little cleaner.

if you guys think back there use to be an after market product that injected water into the fuel system and had claims like 15 or 20hp. my father in law used something like this water injector on his 64 ranchero. didn't last long.
