Pontiac Catalina 2+2
The regular Catalina was a great looking and decent selling model. But in 2+2 form, it transformed into a true Gran Turismo with a luxury interior and fire-breathing engine. Since the Catalina was a full-size model, it was eligible for engines over 400 CID according to the GM rules of the time. This meant that the Catalina 2+2 came with the famous 421 V8.
And you could get the Tri-Power intake system, which was the same as on the GTO. It boosted the Catalina’s power to 376 HP. Also, buyers could order limited slip differentials, heavy duty steering, brakes and more. This made the Catalina 2+2 was well appointed, but unfortunately, it was expensive, too.
