I love old muscle cars, but I just bought a Dark Horse with 500 horsepower from a little tiny V8. If this engine had been available in 1969 or 1970, it would have been an absolute legend.
GTO had a redline of 5200 rpm. I sold my 66 GTO a few years ago, almost cried, but the Dark Horse blows...
I'll try to remember to get a picture and post it, but here is what Blue Ember Metallic looks like, at least in the sunlight. In cloud cover it is like a subdued grayish blue, almost flat, and in heavy shade or at night it looks black.
There is orange (ember) metal flake in the paint.
