Heres another racing legend, the 681/2 428 Cobra Jet Mustang. Modified or stock? This beautiful stocker is concours restored and needs to stay that way, but what if you found one in the weeds begging for a new owner? A lot depends on the cars history and how it was ordered to begin with. If theres no history, you can always build a streetable, period drag car that emulates the NHRA Super Stock champs of 1968.
