I have heard a fair amount of problems with the MSD Distributors but not much from the other MSD components.
I have the original Ford dual point, although the points have been replaced with the PerTronix solid state ignition, and I run the MSD 6AL box with MSD blaster coil. No problems at all in about 4000 miles of driving with any of the MSD pieces I have.
I also did a touch test on the top of my distributor when timing once. I must have had a leaky plug wire because it shocked the hell out of me
Yep that extra voltage is present!
