No Ram Air 400 GTO were made in 1972, only a regular dual snorkel air cleaner and large valve heads 7K3 same as my Lemans 400 engine. The 455 HO GTO's had the round port heads and dual snorkels open on top to get Ram Air in the Qjet carb from the hood openings. This GTO is fairly priced if it's not to rusty on the body and floors, in Quebec who knows ?
