PONTIAC Grand Prix (1970 455cid w/rare 4speed, of which only around 500 were made)
A truly overlooked Luxury Performer. One of the top car magazines back in the day tested a 390hp1969 H.O.428cid Grand Prix and reported times of 0-60 in 5.5 and a 13.8 quarter. This 1970 455v8 Grand Prix in the video was rated with 20hp less (370hp for the 1970 455) due to emissions detuning for 1970. The 1970 455 was basically a larger (stroked) 428 with some emissions detuning.
