No but I know whereof you speak. Recently came across an extensive article 
and if I can find again will pass it on. Problem was that controls were 
crude back then and the first GM air cooled engines were just not reliable 
something that was still in the minds of GM top execs in the late 50's. For 
more information search on "copper cooled chevrolet"

 From memory & web it was a longitudinal, front mounted upright four cyl of 
135 cid and 22 hp @1750 rpm

The idea of the parts and complexity savings possible with air cooling had 
always been attractive to the bean counters and a challenge to the 
engineers, in aircraft, there were more air cooled engines than liquid 
(though the Allison was liquid cooled) but for an airplane the usual air 
temperature was on the frigid side and there was no problem with airflow.

However all through GM's corporate life there have been some that looked at 
air cooling and went hmmmm.
