Mach 1 and Cobra


Do these two have the same engine aside from the supercharger, or are they two different engines?

Well I don't have a chart like ChrisJ, but I do know that the Mach's have higher compression ratio's than the cobra's, also I think the 03/04 cobra's have all forged internals, because of the supercharger. But Mach 1's are still the best in my biased opinion!

The same in which aspect? I don't know if they would carry a completely origional cobra engine, it would be most likely upgraded in some way.

They probably have something pretty comprable. Most likely better.
