GM HEI low resistance brush OK?
I have a 87 stock Vet with a stock factory ignition. Nothing special. Accel has a low resistance brush for use on the HEI large cap distributors. I am concerned why the factory didn't go this way in it's design study on these units. I am runing an Accel 8225 coil on it now and wonder if it would hurt the ignition control module and or the coil should I install the low resistance brush. If you are runnng this brush, please let me know if you have experienced any problems as a result and if so how long have you been running it.
Thanks
Gary

Thank you for the information. My understanding is the MSD 8225 coil is a standard replacement for this HEI.

It's been a long time since you've probably seen "GENUINE" Delco ignition parts! Unfortunately but if it's NOT some very old NOS inventory it's likely some very generic repackaged material and likely not done to the original specifications.

got a pt there ....WV..
I recall looking at a Delco box not long ago that had the "made in mexican" stamp proudly displayed on the end flap.
probably at the same place where accel & msd is made !

I do have concerns with auto electronic parts outside of the country. However, assuming all ignition parts are to specifications, can the lower resistance brush damage either the cap or/and ICM?
Thank You

Determine what it is that you've got in hand and maybe "google" could enlighten you on what's being sold out there. You can't be the first who couldn't make the decision!!!

I installed an msd 6 with a high voltage coil years back. After running it for a while I found that around the stock bushing the cap was starting to burn away. I replaced it with msd low resistance bushing and the problem went away. It will keep you from damaging the cap. It won't hurt the icm either.

I had a heck of a time getting an ignition for my engine when I made the swap to the Pro Flo intake. That intake needs a small cap hei so I bought a supposedly new one from a seller on fleabay. I also did the upgrade to the 165 ecm at the same time. When it came time to fire the engine it just would not run right. Considering what I had done I was centering my attention on the ecm rewiring. I spent days retracing every single wire in the ecm and got no results from it. That's when I decided it had to be the "new" dist. It was supposed to be a Summit brand but when I got to checking I have no idea what it was but it was not Summit. I bought a new Pertronix dist. and coil. Put the Pertronix in and the engine fired right up. I started to do the idle air & timing settings when the engine did all sorts of crazy things, then died. A brand new Pertronix ignition module had died with about 10 minutes run time on it. I bought another Pertronix module and then took a short trip of less than 300 miles. Just as I got back in town, module #2 died! That is when I had enough of Pertronix. I just could not afford a new GM dist. so I settled on a new Cardone unit which was half the price of the Pertronix crap. I have had good luck with Cardone so that's why I bought it. I also ordered a new AC-Delco coil. So far all is good, the engine even sounded crisper with the stock pieces in it. Sorry for the long story but my choice even for a modded engine is plain old stock when it comes to ignition.

Thanks Midnight for the info. I bought the Petronics hipo coil and ICM. I decided to shelve them as I got concerned with them running higher voltage to the coil through the ICM. You're misfortune verifies my concern.
Tell me something, are you running the low resistance brush by chance? I wonder if the different material used to lower the resistance will chew up the rotor contact.
