Because there was little difference between these two years and the 1974 model run was only a few months long (ending in March '74) I have grouped the two model years together here on the same page. Listed below are only the changes from the last years production. Please refer back to previous model years for more detail.

Body

There were a very few minor changes from the '72 model. The front bumpers had to change yet again due to new laws and were now built to take a 5 mph impact with no damage. They looked heavier and protruded farther from the car. The large rubber pads on the over riders and slots to take the bumper jack allow you to quickly tell these models from the '72 version.

The Rallye model was no longer a model in its own right but just a option package for the base model.

Exterior Paint

Challenger Rallye still had the dummy air ducts on the front fenders with the strobe stripe extending along the door but the base models could now have a painted accent stripe that traced the upper contours of the body.

There was a huge range of colours available to Dodge so there may be the odd car finished in a different colour to the ones listed below. You can see a paint chip chart for 1973 HERE and for 1974 HERE.

Vinyl Top

The 1971 gold colour came back for '73 and '74. The other colours remained the same.

Interior

Very little change here either. The seats were reworked for more comfort and the pedal pads were slightly different.
Interior colours were Black, White, Blue and Dark Green.

Brakes

Power front disc brakes were still optional but were now the re-designed one piece rotors. These do not fit the earlier models.

Wheels and Tyres

Only 14 inch wheels were available but could still be had in the Chrome Road or Rallye styles with a 5.5 inch width.

* Only with heavy duty suspension. ** 1973 only. *** 1974 only

Engines

The six cylinder 225 c.i. engine was dropped. This left the 318 as the base engine with the 340 4bbl optional in '73.
The 340 was dropped in '74 in favour of the 360 which had better low end torque. All engines now had electronic ignition as standard as well as hardened exhaust valve seats for unleaded petrol.

**1973-74 Engine Options**
Option code	Size (cu. in.)	Size (c.c.)	Type	Carb.	Net Power (B.H.P.)

1973 & '74 Production Figures

As there was only one model now I have not made a table of figures as in the other model years. Also the six reference books I have all disagree on the number of cars produced so take your pick.

1973 production was (pick one of these)

27,930
30,221
32,596

1974 production was (pick one of these)

6,063 (I am told this figure is for cars with the 360 engine)
11,354
16,437
