No, the inference is you were calling BS on a others and you're right about nobody caring about a plastic fantastic.
I'll put my friend's radar (he's a CT State trooper and car nut) against any factory speedo. You're also right on them being off. My cuda's 150mph speedo was pegged and the radar showed the it was off by more than a few mph. But, I went through his trap at 147. With a 4sp, 3.23s, 27" or so tires, in 4th, at 6100, with the NO2. If you don't think that's good enough to post because "it's not an A Body" and "not a drag racing speed" that's all you. I have also been 127 in the 1/4, but in my opinion that's not nearly as scary as going around curves and up and down hills at a faster pace. I had that Newport sideways around a corner on the highway at over 100 too. There were 4 witnesses in the car with me that night. (I'll add that was a long time ago... I wouldn't do it with passengers now.)
