Hmm. More cam isn't going to make it more
detonation prone, it's less cam that does that.
Factory scientists carefully selected a cam for
the 1967 428 ci HO YK Code Pontiac that didn't
detonate. Even inferring that a former gymnast
and his roommate failed to adequately tune the
motor is tantamount to heresy. And 067 heads?
They don't detonate. Ever.
