Highway Revs

In 1977-1980 I drove my Cuda everywhere with 4:56 gears and a 440 6-pack. Very seldom was I ever on the highway but I remember going to an Oriole game in Baltimore which was about a 60 mile trip south in it and top speed was around 50 mph. Took forever to get there but that thing was over 4000 RPM the whole way. That car was so much fun on the street my first 3 years out of high school. My dad owed a gas station back then and he cut off my credit for gas because I was charging over $100 a week. Some days I would have to fill up the tank twice a day. I drove it like I stole it! But I never hurt that engine from high RPM's! And I dragged raced it almost every weekend during those 3 years.
