Engine Masters had a great show on Motor Trend regarding that very subjectI've run the FBO boxes in multiple cars for 10 thousands of miles with no failures.
Reliability is what I want.
It's about quality.
UTG has an interesting video about points verses HEI and dyno results.
IF wires are "stock" sizes , how much "extra" power/performances can one expect to push through stock wires and stock connectors.
Claims of dramatic improvements don't make sense to me.
Previously had a MoPar Orange box ECU. I had also tried out using an MSD 6AL....but I didn't like the unit, and it didn't fit with my restoration, so I got rid of it.And you where comparing this Dyno Run / Rev N Nator ECU to what ignition box prior ?

Bare terminals on coil circuit, close to frame rail. Temporary?
That will certainly work for for you. They do make rubber boot terminal covers, don't usually see them on cars. I used them in several places in the airplane that I built. Aircraft Spruce and Specialties would be one source. If this had been my car, I would have mounted the coil and FBO module in the normal places, but that's just me, nothing wrong with your installation. Glad that you got it cleaned up and best of all it works for you!
