Hello Thomas,
I wonder if I might ask just why you might want to do this? There must be 
some reason. It certainly would run, and probably pretty well too depending on 
the compression ratios you got for each cylinder combination. I guess if it was 
some kind of economic problem that prevented you from using the same 
combination for all cylinders I could understand it (such as the poor college student 
who got these different combinations for free) it would be understandable. But 
it would disturb the senses of any Corvair mechanic to tear-down an engine and 
find this combuination.
So short term, you might get some high speed vibration (did you balance all 
these combinations?) but run it will, and good too. But long term, It will be 
hard on the crank and maybe some other parts too probably causing a potential 
to reduce the engine's life expectancy some.  

But again, why would you ever want to do such a combination?
Regards,
Bob Helt
