And, for  my last discussion point, I hesitatingly ask -- what is the  
difference?  Seems like back in Nov of 2007, nobody, and this  included 
Bob Helt and Lon Wall, could precisly agree or explain some of  the 
differences.
 
OH? Really??



If they both used the open heads with the 95 having flat-topped  pistons, 
and the 110 the "domed" pistons, what I want to know is where did  GM 
find 95 horses by reducing the compression ration in the 95 motors from  
the earlier squish design?  Or, are the horsepower figures for the  68's 
and 69's simply bogus?
GM didn't reduce the CR by enough to make a difference. !!!!!
All advertised horsepower numbers are bogus anyhow. They are made up.
Actual dyno testing showed the 164 110 hp at 88. No horsepower tests or  
actual numbers were released by Chevrolet for the AIR engines. All advertised 
hp  ratings are bogus, some are just more bogus than others. Probably 
depended on  what they were smoking that day too.

I know that different head numbers are  listed in Clark's catalog, but 
what are the actual differences in the  castings?  Are not all open 
chamber "smog" heads the same?  Are  some more "open" than others?  They 
all "look" like 180 turbo heads,  without the special turbo features.  If 
I had some some of each, I  could cc them myself, but I don't, and 
anyway, if you've ever cc'd a batch  of heads, the volumes are often all 
over the place anyway.
 
The same head casting and machining was used for all AIR heads (not  
including human air heads. ggg) according to Corvair engineer, Bob Kirkman. 
 
Are you not aware of the head listing and analysis done by Bob for the Tech 
 Guide. It's all in there. Take a look.

Inquiring minds want to know.

Thank you,
