Thats what I was worrying about. It is going to be for a 1970 SS with about 550 HP and a tremec TKO-600. I like the idea of factory appearance but I also like the idea of having a more precise gauge.Something to be aware of is the fact that some tachs can lag quite a bit behind the actual acceleration rate of the engine. You could actually be shifting a few hundred rpm higher than you think. They could still be accurate at any steady cruise rpm.
I like that idea, has anybody done this and have pics of the work. I just have a basic SS dash but am very tempted to go with the full SS gauge package. Like I said though I am hesitant to trust the accuracy of these gauges vs. autometers like the tach and the oil psi, temp, vac. ...etc.Install hidden shift light, eg. use park brake lamp as shift light.
