Hey everyone, i have a 2000 mustang gt, looking at it, there are a few things that dont add up, one being its non pi. im guessing that it may be a swap out from maybe a 96-97-98? the oil filler is on drivers side, is there any way i can id this engine to give me more of a idea to what it may of came out of, also, is the bottom end of these all the same? would a pi head and pi intake swap make it the equivilant to what would have come in the 2000? im new to all this and am trying to learn my way around the mod motors. Thanks in advance
