Thoughts on MSD ignition control boxes?

They worth it?

Also would it be best to convert to a different form of distributer ignition or stick with the stock setup?

I like them, I have been using MSD or MALLORY for years,On the TFI cet up I run the stock Dizzy and TFI and "piggy back" the MSD and matching coil in to the factory harness.

It will allow ya to run a bit more gap on the plugs and a bit more advance, so the end result is a bit more power
