Good brands for ignition and other electical

The FBO module does the same thing as the LX-101. They even look very, very similar. The orange MP box pulls out some timing abouve 4K rpm or so (not really a set rpm, but they all pull out timing) Both the orange and aftermarket boxes can control spark well over 6K. I've had stock ones over 7200 before with no problems. They really are good pcs.

Thanks! I just read the section on Electronic ignitions in the old "Direct Connection" Engine manual last evening. It makes a point about making sure that the ECU, coil and ballast all match up.

The stock box works with the stock coil and BR - obviously, right? ;) ... then it goes on to provide part numbers for each of the combinations.

I am wondering if I had a bad combo. The car was a stock factory 340 - late '72 and one of the first with the ECU, prior to '73. It came stock with the 4 pin Ballast. I had the engine changed out in '92 with one of the last of the MP "Commando" (pre Magnum) crate 360s that came with the orange box.

I need to check if I have the correct coil and BR for the orange box if I intend to stay with it and buy another. If I buy a stock box I need to check that I have a stock coil and ballast. The DC manual does not recommend the Chrome or Gold box for sustained 2000 rpm and lower (which I see a lot of). The manual obviously says nothing about the BFO box combo.
