The biggest difference between the old Shelby and the 2011 Shelby is the new car has an aluminum block engine, so the engine in general is something like 100 pounds lighter than before. It also has 10 more horsepower, (550) for whatever difference that would make.
But regardless, new or old, the current GT would most likely waste a GT500 around most tracks, so it doesn't really matter how fast a GT500 is in relation to an M3.
