MSD or not

I run for MSD myself, but my car is not a 68 GTS H code 383...
I've never had reliability issues with a stock ignition except for maybe a ballast resistor which every Mopar guy knows to keep the $5 ballast resistor in the glove box...
Also I never had any liabilities out of my MSD, but I can say one thing I went from Total stock ignition to Total MSD ignition and didn't gain 1000th of a 1/10 in the quarter mile....
