8k rpm ...

If I had to shift my stuff at 9000 rpm to run 11.70’s I would buy a camera and put and LS engine in it. Sorry but there is not excuse for doing that.

Happily, just wanting to do it may be a good enough excuse. I remember Dad racing his 273 4-spd '65 Dart and saying, "Dammit Jimmy, I missed a shift out there and the tach said 9,300 rpm and it was on it's way DOWN!"
