ok i was looking into restoring a 1970 mercury cougar and was wondering from a performance stand point which was better? i noticed the fmx was offered as like a 74 dollar option for the 1970 mercury cougar but i don't know much about it, what made it different, what made it better ect... could someone please give me some information on it, particularly the fmx, but the c6 as well and witch would be better paired with a 351, 302 windsor, or say the 427
