What they said. However, the 65 and 66 models had 389's that had 335 hp with a Carter AFB 4bl, and 360 with the tri-power set up I believe. In 67 GM bowed to pressure from insurance, environmentalists and such and banned multiple carb set ups (read tri-power) on all vehicles except the corvette. So in 67 they bored the motor 4.12 and made it a 400 cubic inch. It came with a Rochester Quadrajet that gave it 335 hp, or you could get the 400 HO that had 360 like the old tri powers. I've had both and actually prefer the 67 variety, but it doesn't sound as cool. I don't think the song would have been as popular. "Little GTO, really lookin fine. 4 barrel and a his and hers automatic, on a 400...stops on a dime?"
