msd streetfire ignition

We are running a Street fire ignition setup on my dads 72 high compression 318 (bored .30 and zero decked) works great still using a stock magnetic dist.

My understanding is they are sorced out to china, etc to make a cheaper product with similar functions as their 6A,Al products.

In all, for a street car it will be perfectly fine. But in my opinion the stock mopar elec ignition is pretty good too.
