Ive Been Wondering If Enyone Knew The Fastest Quarter Mile Mustang Run Ive Seen 5.274 Is It The Fastest?

I'm not really sure this one can be answered. At the highest levels of drag racing the cars may not have a single OEM part on them but they may mildly resemble a "mustang". A tube chassis funny car with a "mustang" fiberglass shell in my opinion is not a mustang. Pick up an issue of Muscle Mustangs and Fast Fords and you'll get some idea of what different classes are running.
