i've heard that the 1993 sc motor is all by itself. is that right? if i go to replace this motor do i need to only use another 93 motor or can i use any other year but just change over my 93 parts. Has anyone ever used a new motor from ford? or would i just be better off rebuilding mine. i would like to keep it stock for now,after i see how this handles then i can do more with it. any help would be appreciated.
