GTO 455 Drive
Glamor shots of my 1971 GTO and a spirited drive around the block. Shaky camera work but some nice sounds from the 455. The motor tachs to the redline a couple times.

Camaro Z28 messing with 455 GTO on the street
Late-Model Camaro Z28 with bolt-ons messing with a classic 455 swapped GTO. The GTO jams it and then one of the passengers thought they were being tailed by an unmarked B4C (special service police) Camaro holding a radar gun (video camera, lol) notice the nervous and unsure look on his face as we roll beside, then his complete and total relief once he recognized a couple old pals in just a regular Camaro, lol. (This Camaro made 280hp at the wheels and ran 13.1 at Mason Dixon Dragstrip) This footage was shot way back, many years ago, with an old junky analog camera, so apologize for the poor video quality.
