The S7 not really being any faster than the GT is news?
The GT, and in the case of the S7's big pushrod block, these engines are a testiment to the value a large lump of an engine. So much power can be brought out of them with reletively simple modifications. They're just so tough and robust, this is why they will always be the preference of many over a lighter, higher revving design.
Never a sexier car will there be than the XKE? Sir I challenge you to a duel.

Sure, it's a slinky little sports car, but come on.
