There is no need for dimension modifications, as the new engine will fit into the engine bay of the Modena. As I said before, although Ferrari claiming the 420/430 to be a brand new car, it more looks like an evolution of the 360 to me.

BTW, spoke to my dealer. The Modena is no longer available. His last car for a customer is due in May. Spider will be produced all over 2005. His last Challenge Stradale will be delivered approximately in November. So I guess we will see the 420/430 at the earliest in Paris and delivery will start around spring next year.
