The '99- up GT's have what are called PI (Power Improved, Product Improved, whatever you think it stands for) heads. These heads flow considerably better than the non-PI heads on my car. The intake manifold is also slightly different on the '99-up's. Another difference is the newer GT's have a returnless fuel system (Doesn't effect power though).
