I had a '69 that I had picked up from a friend I knew in high school, he had the motor set up on him when he started it on a cold morning, at the time I was working at the local gas station & repair shop, we put the thing on a lift one night and wedged an ice breaker bar in the flywheel and started to let the lift down which was the old air/hydraulic post style, by the time I caught up with the lift pressure the front of the car was a good foot off the lift and the motor broke loose, she ran after that, but knocked bad and blew up 2 days later... ahh memories.
