The Chevelle SS was a sweet machine, but the fastest ride I ever had was 140 MPH in a ‘69 Roadrunner with the 383CID and 3 2-barrel carbs. One scary automobile!
Same in a 69 Chrysler with the “small” 440. It took awhile to get to 140 on a stretch in Indiana. But the 2.76 rear did it.
How do I know it was 140? I had a SW speedometer instead of the factory.
At that speed it seemed like it wanted to fly off the road. I added a set of Koni shocks and cranked them up.
I used to drive 600 miles to college, in less than 10 hours. I hitched a ride when Dad died from school at 6:00 pm and made it home before breakfast once. 64 4-door Dodge.
