Some creative thinking to get it to market

This new GTO came with the same rugged 389-cid V8 powerplant as used on the larger-sized Pontiacs, but to give it even more potency, the cylinder heads were from the 421 H.O.. The standard version came equipped with a single four-barrel Carter carburetor, with power rated at 325 hp at 4800 rpm.
