some of the yank "sports cars" are nice now, the modern v8's are so tunable, i think the gt500 engine is basicly the same as the new GT40 engine, and the youtube video of joe's GTTT shows what they are good for, anyone that hasn't seen the video, by replacing the supercharger with twin turbo, and remapping the factory ecu, they got 1012 bhp at the wheels, not the flywheel, the wheels, and the guy used it for street racing and it was reliable, not bad for a stock factory engine!!!!
