Yep I agree, and it will run 87 octane too.
I called it early on, I mean...I could maybe accept that dynamic with old open chambers and no quench...but rhs closed chambered heads, hmm.
Oh is that what he's runnin? I honestly didnt pay attention there........If that's the case, then I double down on agreeing with you. Closed chamber heads with .039 quench is good for 11:1 with the right stuff.
I just assumed this was regular open chamber crap.
