Wuzzup y'all? I'm new to the mod 4.6 world. I've spent a lot of time on my wife's '98 V6. So, where do I begin with my Mach 1? In most catalogs and magazines, I see parts listed for GT and for Cobra. Every once in a while I see Mach 1 part. Is there a rule of thumb when searching for parts compatible with the Mach's powerplant? It seems that is a vresion of the '99-'02 Cobra mill... Any help would be greatly appreciated.
