Very interesting local car?

I saw this car at Fry's Electronics a while back. Also saw it on sale in the Autotrader for some hefty price $$$. I believe it has a pulley (from the Autotrader ad), which the dealer neglected to mention. If that is indeed the case, 500 HP is easily attainable.
 
I saw that at Thomason when I was on my way to pick up my 03. It's even fuglier in person, truly an abomination.

There's an engine pic in their ad -- I can't get the full size version to pull up in my browser, but it sure looks pullied to me. 500 crank horsepower is trivial with a pulley. 500 rwhp without at least a ported blower is impossible.
