Distributor

The Chrome box has worked very well for me.
The Orange box pulls timing out of the high end.
"Other boxes" have been from OK
To very nice with marginal gains, if any, over the Chrome box. I had an FBO box which was very good. (Sold with other car.)

The MoPar distributor can be a funny peice. I have not had a need to go crazy on it. Some people end up welding the advance plate inside. Limiting the total.

I now am trying the Pace ready to run. Just like the MSD. I just haven't had the time to field with it yet.
