the mark8's have the same cams as an 03-04 Cobra/Mach...they are much less aggressive compared to the 96-98 Cams. The early 93-96 mark8 intake is a very shitty design, and the 97-98 one is better, but still no where close to a Cobra one. The oil pan on the mark8 is different too, as well as the exhaust manifold. They also have a 6-bolt cast iron crank instead of the CObra's 8-bolt forged crank.
