Rare 7.4 Liter: 1974 Pontiac Trans Am

While other muscle cars were being gutted of their performance engines, Pontiac continued to offer both a 400 cubic inch V8 engine (6.6 liters) and two versions of the 455 cubic inch V8 engine (7.4 liters) in the Trans Am. This paid off because sales continued to increase for the 2nd generation Trans Am all the way until 1980 when Pontiac reduced the engine size to 301 cubic inches. This 1974 Pontiac Trans Am is located in Lockhart, Texas near Austin. It is a  red with a black interior project car. The Trans Am is listed for sale for $10,000 here on Facebook Marketplace. It has been listed for about 2 weeks.

This car is definitely a project car with partial rust work performed on the floor boards. There is also rot around the rear window. The 1974 Trans Am is the last 2nd generation Trans Am with the flat back window. After 1974, Pontiac introduced the wrap around rear window which continued until 1981. This car also has a 1976 front end and bumper which, in my opinion, is a really clean look.

As mentioned above, the base engine for the Trans Am was the L78 400 cid V8 engine that produced 225 horsepower. A buyer could opt for a Y code 455 cubic inch V8 which was rated at 250 horsepower. That is the engine that originally came in this car. However, it is long gone and a non original 455 engine comes with the sale. Another option in 1974 was  the King of the Hill Super Duty 455 cubic inch V8. Only 943 Trans Am were produced in 1974 with this engine. It was rated at 290 horsepower. I owned a Super Duty 1974 Trans Am for awhile and I would say that its horsepower numbers were understated.

You could order any Trans Am in 1974 as long as it was Cameo White, Buccaneer Red, or Admiralty Blue. This one is Buccaneer Red which is Code 75.  This car comes with a GM Turbo Hydramatic 400 automatic transmission. The seller states that a number of new interior parts including seats, headliner and carpet are included with the sale.

    The SD 455 was very understated. Friend of mine, that recently built my 355 SBC, rebuilt one for a client. Took that and my motor to be dynoed. The 455 only had a cam, headers, and a Holley. Made 420 HP and 510 TQ. When it was running on the dyno it felt like it was punching you in the chest. Definitely a stump puller
