Considering that's a late '50s design, beats the pants off of anything else of that time - according to Chuck Daigh. IMO better looking than the 289 and a toss up with the 427 which came 8 years later.
“There was really no competition for us. There wasn’t any car in the world that I couldn’t beat with the Scarab. If we had raced against the Mercedes or the Ferraris or the whatevers, we could have beaten them – easily.”
