No Dude thats wrong!The last 455 Pontiac made was in 75.After that76,77,78, was a 400,Ford had nothing to compete with that.79,80,the 6.6--401Olds motor,still ford had nothing.Even in81 Pontiac had the 301 turbo,Ford couldnt even beat that.It was untl 85 when the mustang came with the roller cam,that ford startsd to rule!
