<VV> Corvair Specific: Gas freezing?

[Jim Davis]

Well, all of this discussion of temperatures and pressures is applicable 
to Corvair powered UltraVans.  Using a Corvair engine with PowerGlide as 
the drive train, we usually need all the torque the engine can muster.  
In the Rockies, I always re-jet the carbs (fast jet change mod on the 
HVs) and bump the ignition timing up.   You would never make it over 
Slungullion Pass (11,500+ feet)  in a 5,400 lb UltraVan without getting 
every ounce of power out the engine.  Dropping to 48 jets and adding 5 
degrees of advance above 5,000 ft really helps with the torque.  If we 
are going to be in Lake City, CO (8,761 feet) for a week or more, I add 
more timing and go down a couple more jet sizes.  If I get too 
aggressive, the Safeguard will save me.   If you are ever in Lake City 
bring your fly rod as the fishing is beyond fantastic.
