no the mach 1 motors are iron block, aluminum head 32 valve dual overhead cam engines like what was in the 03 04 cobras minus the supercharger. also the mach 1 motors are pre 2005, i cant remember for sure but i belive they are 01-04. i was just giving you idea of what it might cost. in my opinion the the cobra or mach motor have a lot stronger bottom end (malhe pistons, forged rods, ect,ect) if you want to go stock motor with minor mods i would go with the 05 up 3v 4.6 since it is a lot lighter due to the aluminum block, but if heavy mods are in the plan go with the cobra or mach 1 motor.
sorry for the confussion
