1972 Pontiac Firebird Trans Am

The 1972 Pontiac Firebird was a difficult year for Pontiac. Due to labor troubles at the plant and changing emissions regulations the Firebird lost some of its former powerful image. This included new horsepower ratings and some signifigant changes under the hood.

If you ordered the Trans Am you received only one motor option - the 455 cid. The 1972 455 motor featured one year only set of heads that retained much of the flow rates of the earlier models. Combined with a 4 bolt block, true four barrel carb and a warm camshaft this meant for a spirited engine. The air was fed into the engine through a true cold air reverse facing hood scoop. Interestingly, this was the last year the scoop actually inducted cool air.

The motor was mated to either the Turbo 350 or the Rock Crusher M22. Again, combined with a steep gear ratio meant for a potent combination.

On the outside the car received new honeycomb styled wheels and a slightly revised grill. Interior changes were minimal and featured new seat coverings and styling.
