My boss recently received his Cobra replica. It has a 427 built up on a small block, with about 650hp at the crank. It's lumpy as hell, to the point of being almost obnoxious. After an extended ride in it, I decided if I ever had the money to do something like that, I'd just get a BMW Z4 with that silky smooth I6 and build it up a little. However, if I really had that kind of money, I'd get a MonoTracer.
