The Windsor head design is less susceptible to detonation then the closed chamber Cleveland is. Put another way, the closed chamber Cleveland head is one of the most sensitive I have seen to detonation.

I heard you car in a soundbite (thanks, it was cool). I doubt very, very seriously if you would actually hear it in that car. It's a little bit loud.

A lot of times in the Mustangs, in order to hear it, you need to take off the shifter boot. That's what I do.

During the fuel shortages we had here in the '70s, people were running the cars on whatever gas that they could get.

Many of the 10.5:1 289 Shelby GT350's and Cobras were running on regular, which is 87 octane, without pinging or detonation.

It's just a benefit of the shape of the combustion chambers.
