I would  expect its economy to be outstanding at highway speeds with the 
tremendous  ignition advance specified for this combo. I also wonder if there is a 
special  distributor or vacuum advance unit used on this combo, seems the 
usual 110  distributor would be rather excessive for advance,

Any advice or  experiences would be very welcome,

Hi Brent,
I have no experience with this kind of setup, but can offer some thoughts  on 
the subject. First this setup was used only on the 1966 and 67 110 engines  
with powerglide. Not any with MT. According to all the Chev specs, these 
engines  all used the standard 1110319 distributor, same as for the MT engines. They 
also  all used the same VA as the 110 MT engines.
The 110 engines with both PG and A/C used a static timing of 24 degrees  
compared to the 14 deg for the MT engines. By doing so, there must have been  some 
kind of problem the factory was trying to sidestep in my opinion. And  
remember, really high octane gas was then available then to counteract any  
potential detonation problems. Using so much advance (24 initial+ 20 distr = 44  deg) 
seems to have placed the spark timing way past MBT and must have been done  
for cooling. At any rate, I'd be suspicious of such a setup having this much  
timing with or without 8:1 heads. This would be especially true with today's  
octanes.
Just my opinion. You may get other thoughts.
