FBO or MSD what do you use?

If you read tuner sites like Megasquirt, the consensus is that the best ignition is distributor-less single coil per plug systems like almost all recent engines use (Mopar's Hemi). There are always compromises when plugs must share a coil, especially at high rpm. The GM LS coils are easiest to adapt since they have a built-in ignitor. Simpler is the Ford EDIS which many Megasquirters use, but has 2 cylinders sharing a coil ("wasted spark"), which requires only a crank sensor. The dream for my 273 is LS coils triggered by EDIS combined w/ Magnum cam sensor. I have most parts. Of course, this isn't a "write big check" system, but can be cheap (my motto).
