I was talking to my friend, and his dad happends to have a Pontiac Grand Prix GTp Supercharged 3.8. He told me that its redline is at 9k. I explained to him that it's incorrect. I even know that No Stock American Car rev's to 9k. Someone support me here.

[hr]You are right.... I don't know of any american car that high other than some custom built jobs like saleen s7.
Most american engines tend to have single cams and top out around 6K - 6500
