I was just wondering about all of your opnions on the MSD HEI module as opossed to the 6 series boxes. Obviously the box has a higher peformance potential but the module looks good too. Its nice and protected under the cap with no extra wires or splices. I also like the idea in that the event of an unlikely failure, another drop in module will get things going again. I already have the MSD coil. The $70 price tag also is a little more friendly. The module is supposed to drive the coil 50% more and increase the RPM range for firing.
