The 427? I didn't know if they ran big blocks at Le Mans. Thanks.
Ford had a hard time selling enough GT40s for homologation in the 1960s and had to sell some for less than cost. Today they sell at auction for over $1M. In 2005-2006 a special run of Ford GTs looking much like the GT40 were produced. There were 4,038 produced at an MSRP of around $150,000, but dealer premiums were charged. Today those sell for around $500K. The new Ford GT will have limited production, I think I saw production of street cars around 400 and price starts at $400K.
The Ferrari 488 seems like a really great street car. Twin Turbo 4.0L V8 making 660hp. The race cars have to add restrictors so the street cars are more powerful than the race cars. They cost much less than the Ford GTs at the $250K range base price, but the back order time is now 2 years, I checked.
