Like all of GM's other A-Body vehicles, the Lemans got a fresh makeover in 1968 that carried through 1972. Along the way, its 350 cubic inch engine was bumped up to 330 hp while its 400 and 455 cubic inch siblings became optional powerplants even without the GTO nameplate. In addition to those powerplants, you can now drop in a Gen III/IV small block with our LS swap systems.
