FBO ignition syste

I have one, comploments of Don. In testing, it seems to be a hair better than the Chrysler Chrome box in my lowly '78, 400 cid HP motor. I tested it vs the MSD 6A, Orange and Chrome box's.
For the price, it can't be beat.
On performance and mileage, it stands toe to toe with the MSD @ cruise/Hwy. speeds.
Idles better than the MoPar boxs. Not as well as the MSD with it's multi spark advantage, but that advantage is gone after 3000 where most hot engines live and work. The MSD advantage is gone and is no better than most any other ignition.
I wish I could give you a spark plug report, but T-Q problems persist. But there lasting longer over the leanburn and Orange box noticeably.
