Tk,
That's the way it was advertised. I reckoned it's probably a misquote. My bet is that it's a 351 (still) and has just enuf trick stuff to yield 390 horsepower!
In any case, it'll soon be a 406 ci. I think I'll change my intro, to avoid confusion.
Everyone,
As to the propriety of "wearing" the decals/racing livery---I'll do it temporarily for DVSF III (if the car's done in time)...then go out to the driving clinic at Lime Rock or Lauden....
