The GT is listed at 3,400 lbs. and the 430 is a bit lighter at 3,200 lbs. This would account partly for the similar acceleration times, despite the power difference. But it is interesting that they are so close, since mechanically they are quite different.
Thunf mentioned something I was thinking about when someone said that
Ferrari builds the best NA engines in the world. Ferrari are indeed masters at creating the most horsepower per displacement, but as we've learned in the very popular
Engines thread, "best" can take on very many meanings. What about torque per displacement? Fuel efficiency, reliability, flexibility, cost of maintenance? Ferrari would surely rank fairly low in some of these. And Bleh, I trust reliability would not be an issue with the GT since it's a highly developed $140,000 Ford for one thing, and also being powered by basically a highly modified truck motor, represents one of Ford's more reliable aspects - their truck manufacturing. In the case of the GT, " Built Ford Tough " I think would apply.
* Zit, we had a "Capri" over in the U.S. years ago. But it was basically a Murcury Mustang, and later on took the form of a small two seat convertible.
