My 1st car was a 1958 Ford with a 312 T Bird motor. It had a hood scoop which had an emblem which was just a styling cue. However, I knocked out the emblem and installed screen wire in its place. It was then a real hood scoop.
On a rainy day, that car was very noticeably faster. It was somewhat of a thrill to drive except for one problem. The windshield wipers were vacuum operated. So, if you really accelerated hard, the wipers stopped. That feature probably saved my life. I was 16, wild and crazy and didn't care. IOW I was the typical 16 yr old...
