My dilemma with fuel is I can get ethanol free fuel at 91 octane, or I can get fuel with up to 10% at 93 octane.
I’m having the aluminum head ported and polished. The issue I run into is if I use a dished piston by SCR drops significantly to mid 9s, even if I dropped the chamber size to 50. I’m thinking flat top with 53cc is good.
Which fuel is recommended, 91 corn free or 93 with corn?
