MSD yay or nay

I put an MSD HEI module in my RA-III's distributor and it made a world of difference. It didn't drop spark like a hot turd above 4,500RPM like the stock ones do; it pulled well past the point at which my OE connecting rods were a worry. I lost track of that engine years later but still running that module. A good friend had a 6AL in his Charger for 20+ years without an issue. I bought my module in 1990; his 6AL was installed in '87.
MSD has changed hands more times than I can count since 1997. Apparently mismanagement was a way of life there for a long time, hence the repeated sales of the company. It's quite possible things just ain't what they used to be. The only MSD parts I've used since that HEI module were plug wires and a coil, so I can't testify for either side.
