When I had a 73 Westie I had to use the best premium I could find otherwise
it ran like crap!
Lyle Cherry (that may not be the way he spells his name) rebuilt my engine
and before I ever drove it I asked him what kind of fuel to use. He told me
regular is just fine and that is what I have used ever since. I have not had
any problems and my bus runs just fine.

Not so. I run regular octane fuel in both of my busses, and they run fine!
I was surprised when, after running Casper on Hi-test for many years, I discovered he was all OK with regular octane.
-but-
When I rebuilt the engine on NeueBus, I increased the combustion chamber a bit, and lowered the compression ratio just a bit, as well, so that regular octane would be acceptable.
With my conservative driving (slow) and the Hull unit electronic ignition set pretty far advanced, I get 22-23 mpg consistently, and never a ping.
In the higher altitudes, (+5,000 ft) I know for sure that the timing will need advanced, and I could possibly discover that the higher test fuel will again be needed.
Here at 550 ft - 1250 ft altitude, I have no problem.
