"Back in the day" I had a 1971 RoadRunner 383/4 speed. I couldn't beat anyone in a 1/4 mile, but it looked good! Before I traded it off, I took it out and tried a top speed run, because I knew I'd always regret it if I didn't. I was going 143 by the speedo when the farm tractor pulled out onto the road in front of me. He was far enough in front that nothing bad happened, but it did scare the crap out of me.
I went about 125 on my then-new 1979 750 Honda.
It's been years and years since I've went over 100. My 94 Dodge/Cummins farm truck tops out at 91.
