HEI ignition module

Any difference in the brands, or will a stock module do just fine?

Stock module is only good up to about 4k rpm.

I don't know who's are the best or if their is a huge difference between the performance brands. I have had success with DUI and MSD. We used to keep a spare stock module in the boat just in case we lost one. It came in handy once.
