69 coronet 318 2bbl auto. Only performace upgrade if you can call it that was a complete 2" dual exhaust system. I was shocked when it ran 15.69, not only that but it ran it almost every run. Ended up finishing runner up in trophy class ran a 15.71 on a 15.70 dial. Other guy just cut a great light. Here's the car before I put on the magnums. should have kept that car....
