Fwiw,I had a new FBO box that was dead 1st time I tried to use it, but it had been on my shelf for a yr or 2 so I just shrugged it off, put a buddies used Orange on for now. Reading these threads & still haven't decided which was to go,...maybe back to MSD.  Maybe one in the trunk too!  Back in the 80's it was joked about how I could rebuilt my engine on the side of the road from the spare parts in the trunk.

My 72 440 RR has a 5 prong block...My old 72 400 had a 4 prong block and I can find nobody than knows the difference and why ?? The original early (72 ish) electronic setups used a 5 pin ECU with a 4 terminal (dual) ballast. later kit (orange/chrome/gold ECU's had the start circuit combined inside the ECU & no longer needed the extra ~5 ohm half of the "dual" ballast. Aftermarket ECU's are avail in 4 or 5 pin & the 5th pin is a dummy (has no continuity) & was introduced cuz people making parts purchases were complaining that it was the wrong one (comebacks before they even installed it which if they did install it they woulda found that it worked) cuz a 4 terminal (dual) ballast system will work with a 4 or a 5 pin ECU but the parts mfrs just added a fifth pin to stop the complaints/comebacks. An OE 5 pinner ECU with a functioning 5th pin (has some resistance in the red/green wire pin) does require a 4 terminal "dual" ballast. Not sure if this is what you are after but I've been gone all day & I miss my computer time Thanks for that reply..! much appreciated..

Chrome box has a better history. But,for what it's worth if you do a little research you will find the chrome box was designed as a race unit good for 8,000 rpm,and not recommended for street use. My old catalog says orange and chrome street but the gold finned is race. I put a chrome on but do not do street. BTW It does rev

It was as much as 2 yrs since I bought it, so I didn't bother. I mint to call to see about having it repaired & he might've even cut me some slack. But I'm so close to getting this resto back on the road that once I clear a hurdle I'm onto the next. I keep telling myself I can come back and fix this & that after I get this thang rolling, It's only been 32 yrs since it's done that. ...I hope I'm not lying to myself.

i think alot of the orange box failures are the result of folks NOT using a ballast resistor with street use. I thought the box gets full power and the ballast resistor only cuts power to the coil?

According to MP, the Chrome box would have a higher rpm limit than the orange box if the right ballast resistor is used. The unit I always had fail on me in the past was the gold box. I can't remember how many of those pieces of crap I threw out while at the track. I always went back to my chrome box (before I went to MSD, anyway). In fact I found my chrome box the other day. Probably haven't used it in almost 20 years. Still works!

Sorry to hear about the lame FBO Parts.
I had a poorly assembled distributor and a coil that snapped the terminal while snugging down their "proprietary and required" Coil.
Found out that the owner must be a close relative of Richard Sherman since he was about as accountable and cordial during my report!
I've had success with Mopar boxes as long as they are Grounded well.
I've also used Revinators and had immediate success unlike the bad FBO experience.

Correct, but with running no ballast that means the coil pri circuit is flowing more power and the ECU has to open/close that circuit & deal with more voltage than it was designed for & the higher voltage can but not neccessarily make an ECU fail quicker. You have ALOT of leeway on what you can get by with (Carry a spare always!).
