Sorry, I could not look under the hood. From the sound, when he drove in it rather was a modified 289/303, although the aggressive note spoke for a little bit more. I have heard some 390ies, but this one was not like that.
Even Mustang Team members -being mailed the link by their head - had to read it before they worked further on their concept car. Unfortunately they did not listen to us in case of the big gas cap, but in fact I did not expect that.
Do not take this post to serious, but it is true at least.
