the current motor is supposed to be stock and according to the previous owner "it has never had nitrous or a supercharger". the previous engine was built up from a forged short block, the one before that was an '03 cobra, and the one before that was probably the original. 4 engines, still less than 5,000 miles. what remains of the 525hp project is the '03 rear end, fuel tank and dual pump, eibach springs and subframe connectors.
