I recently bought a 04 mach 1 with 38k miles and it ended up having a blown engine. My options are limited to a couple of things. Either attempt to re-build the mach motor , or buy an 03 rebuilt cobra motor without the supercharger. WHAT SHOULD I DO ? The motor was burned out in cylinders 7 & 8. It would need new internals. Any suggestions or does anyone have any motors for sale ?
