The absolute validated fastest I drove was at the Richard Petty Driving experience, 143 mph. But I really wanted to go faster. You really don't feel the speed in those cars on the big oval at Texas Motor Speedway. It was kinda frustrating because the pace car in front of me wouldn't let me go faster.
Other than that, it was 132 mph in my 73 Charger SE 318 car and 136 imph n my 70 Firebird 350 at 16 and 17 years old respectively. I actually believe I hit the 140s in my 73 Challenger 340 in 1990, but with the 120 speedo, I couldn't be sure, but when it was pegged, which put it about 130, I still had a little throttle left.
I don't know what I actually got to, but I was screaming down Hwy 70 between Kinston and New Bern, North Carolina which is straight as an arrow divided hwy with few side roads and lined with tall trees down both sides, about as safe a spot as you can find....unless you leave the road.
The lord loves 2.76 gears and a classic mopar (they bring you closer to God so much sooner
