what was the top speed of the 1969 ZL1??
I have no idea.
It might be possible to calculate an estimate based on the quarter mile times in the neighborhood of 11.5 seconds, but I don't know the right formulas to do it.
I was given an incredible ride in a potent muscle car when I was a kid. Back in the '80s my aunt dated a guy who made a lot of money transporting certain illicit substances across the border into Canada. The police need not worry if they read this, he didn't make it out of the '80s alive, and his ill-gotten gains are long gone. And for that matter the police knew who he was back when he was alive; they could just never prove it in court. Anyway, he gave me a ride once in his "outrun the cops" car.
It was a MOPAR of some sort with a 340 small block. My dad (a mechanical engineer in the auto industry) had helped him rebuild the engine so all the parts meshed with very high precision. Or something like that. (I'm *not* a mechanical engineer in the auto industry, so might not have that exactly right.)
But anyway, wow. That ride is still seared into my memory. The speedometer only went to 120, and we left 120 way
behind. Then there was this S-curve with an intersection in the middle, with the curves rated for 35 MPH. He backed off to 90 MPH on the curves. There was a van stopped at the intersection with some sort of church lady in it, and we simultaneously passed on a double yellow line and ran the stop sign at over 100 MPH. I got a brief glimpse of the church lady clutching her chest like she was having a heart attack. I suppose she got a brief glimpse of a little kid with a huge grin on his face.
When we took those 35 MPH curves at 90 I was a bit worried. There were no shoulder belts in that car, and the bench-seat lap seatbelt was way too lose to hold me securely. I don't know how that car held the road, but on one of the curves the centrifugal force pinned me against the door so hard that I couldn't move. I remember thinking I was dead if the door came open and ejected me. I struggled to somehow stop pushing against the door with such force, to no avail. Luckily the door stayed shut anyway.
That engine was LOUD too.
