We work direct with the factory, and ours come down the same line as other famous brands, and go in BluePrint boxes. I have been to the factory, and actually helped setup the end of line testing, including vac advance operation, tach signal function And clarify, mechanical advance and curve. That's all specific to our requirements. I can't claim they are the same as msd, as I don't know what they still do in TX or not, but I can tell you some of the electronics, caps, rotors, etc, are indistinguishable and interchangeable.
