Correcting the mixture is necessary if you’re gonna run it around Denver but it won’t give you back the performance you had down at sea level. As long as you’re dealing with a normally aspirated engine the power output will continue to decrease and it will get more sluggish the higher you go.
At a mile high the air pressure on a standard day is only 12.2 in.hg. Your engine is only going to let in about 80% of the air volume available at sea level at full throttle.
There are bunches of paved mountain roads in CO. that are at of above 10,000 feet. The pressure of the atmosphere up there is now down to 10.1 in.hg. and an engine is only capable of producing less than 70% of its sea level power.
On your run up to the summit of Pikes Peak you gonna be down to about 55% and probably wouldn’t have enough power to pull the old Stovebolt.
And that’s why they invented superchargers……
