Match Race 1972 ~ 'Road Runner/GTX 440' vs. 'Buick GS 455'

Back in the early 70s I raced a 455 GS that looked like that post photo with my stock 1967 GTS Dart and had a passenger. When I shifted into second gear I pulled 1.5 car lengths on him. I remember being surprised at the time since he had a 455.
