I have never used an MSD in any car I've owned in the past 42 years. I've run the MP distributor with a stock box or a chrome box recurved and dialed in even in a 10 second street car.
On the car's that came with stock dual points I then used Pertronix conversions in them and all was well also.

And will Add the simplicity of troubleshooting along with the availability of parts is another big plus IMO
