well, i shouldnt of said "replacing"....but for a while, the 360 was ferarri's competitive car with lambo....lambo came with something new, so ferarri whipped up the 430...at least thats what ive heard....dont take my word for this
the 360 was a ferrari "selling car" to raise their income. i'm not sure about the competitiveness of ferrari vs lamborghini, but i do know ferrari had been working on this new engine for a while now
