The bad ground theroy is easy to eliminate by simply adding another ground directly from the battery to the engine block. Chances are this is not the problem but it is easy to do. Usually if you have a bad ground on the engine you have other associated problems.

Here is their page to check rotor pahsing: http://www.msdignition.com/pdf/tech%...or_phasing.pdf.
On this page they state that every one of their Pro-Billet Distributors are checked for correct phasing during the assembly process at the factory. Again like the ground it is not hard to check but requires destroying a cap and if they do as they say during the manufacturing process this should not be the problem.

So that leaves the last option. The rotor is not manufactured properly and there is a gap between the rotor and center terminal of the cap. This is easy to check by doing some carefull measuring or placing a thin coating of dielectric grease on the tip of the rotor and seeing if it is transfered to the center terminal of the cap.

It just seems to me they should just make the rotor correctly. For the money they demand for their caps and rotors I don't think this would be asking too much. I also wonder why they don't offer a replacable center terminal for the cap. I'm just kidding, if they make this stuff properly or sell replacement parts for the cap they would not be able to rip you off for new caps and rotors every 500 miles.

Absolutely.
