That's why this Super Commando 440 engine, an original issue to this '68 Plymouth GTX, makes this classic carriage quite the standout. Build way back in March 1968, this gear-slapping Forest Green muscle machine is documented with its original build sheet, broadcast sheet, and Certicard.

Our favorite feature - the 150-mph speedometer, which would be a perfect challenge for the 3.23-geared 8.75-inch rear.

Offered for sale by madmusclegarage, this pampered Plymouth is RYNO Classifieds car of the week.
