1972-3 Pontiac LeMans GTO
The early ‘70s Pontiac GTO was no longer a separate model, but only an option on the mid-size Le Mans. They shared the same body style with sporty details and a few exterior features. However, for the 1973 model year, they redesigned the GTO, making it closer in appearance to a regular LeMans coupe.
The power was down, so the base 400 and 455 both delivered 250 HP for 1972, although the 455 had much more torque for a better performance. In 1972, a rare engine option was the 455 H.O. producing 300 HP, which you could call a true muscle car. However, in 1973, they dropped the High Output version and the 400 V8 delivered just 230 HP, while the 455 got 250 HP.
