The GTO package was only offered for LeMans coupes and hardtops in 1972. The base V-8 again was the L78 400,
net rated at 250 horsepower. A three-speed manual was
standard behind the L78, while an automatic once more was the only choice with the optional L75 455. All transmissions were available behind the LS 5 455 HO, demonstrated here. Photo: Mike Mueller.
