Reply to "Progression Ignition distributor - Is it compatible with our tachometer?"

I have two Pantera projects underway concurrently and one of them had an incomplete ignition system.  Specifically, I was missing an MSD 8577 distributor and an MSD 8920 tach adapter.  After careful thought I decided to try Progression Ignition instead.  The cost is about the same for either approach and the Progression Ignition has a money back guarantee if you don't like it.  At this point I have the Progression Ignition installed in a car and it is working well and the installation was relatively simple.  Duraspark and Pantera Electronics would have cost just as much or more to implement and they would be going backwards in some ways.  The only risk here (as you have pointed out) is longevity and dependability of the Progression Ignition.  Time will tell.
