We'll probably be building a 1275 for a bugeye this summer and I got thinking about what octane level/fuel choice (i.e. compression ratio) that we should consider, and would appreciate thoughts.
1 - not a lot of annual mileage expected each year, which means cost differential isn't real critical
2 - ethanol is generally viewed as a Bad Thing for old vehicles not getting a lot of miles on them, and premium seems to be the only way to reliably avoid it
3 - if the engine can handle lower octane, should we burn premium in it?
4 - if we're going to burn premium anyway, why not go higher compression?
In some ways, this is a bit of a rabbit hole to disappear into. Comments appreciated on points I've missed and any other aspects. Thanks, Doug
