I have a 2004 Vette. Owned it since 2008 I have seen 152 on it's speedometer. The car had more.... but I don't know how much more.
A friend of mine had a 69 superbee with a 440 magnum motor in it.
I was riding, the guy got out on the highway and throttled out.
The superbee just kept going faster and faster.
We went down a hill and i expected the valves to start floating.
Nope, the damn thing just kept gaing speed,
The speedometer needle went past 140 mph.
I turned to my friend and said : ok im scared
