Scott -- I'm so bummed you weren't able to make it. Yours is definitely one car I'd really like to see -- and hear -- more of!
Well, so far, Bob was pretty close, and Mike even closer -- but no one has them all right so far... I guess that makes sense since you two have probably seen these cars in person more than most of the rest of us.
I also wonder if your mental perceptions are influencing your guesses -- like "a Cleveland
should sound like this...". (That's a hint for you Mike...).
I also would have to say that the experiment was a success in the fact that all eight engines sound very different -- at least to me. Of course, when I played them for my wife last night, she just kind of looked at me with that "whatever makes you happy, honey" look.
