Please explain that statement in detail since it makes absolutely no sense considering today's technology and engine design. (Brad touched on this briefly already!)
Maybe if you are stuck in the 70's with low tech pushrod V8's and no engine managements system but otherwise it is very outdated and wasting a great deal of power potential.

10:1 engines running 87 octane are common place. 11:1 engines running 91 are common place.

Heck Brad even ran his ~11-11.2:1 hybrid on 87-89 octane fuel with no detonation problems and still making decent power.

You really need to jump forward several decades in your thinking or at least stop "recommending" others to jump back to that out dated thinking.
