Anybody have had issues with MSD 6AL boxes and MSD coils. A friend has gone through 2 coils already. Any information will be greatly appreciated. Thanks.

MSD coils have been an issue in the past. I am not up on what the best coil to use is right now - maybe a search in the performance subforum would give you an answer that will help.

This is not an issue of the box causing the coil to go bad, it's the coils themselves.

Big gaps are tough on coils. I run a rare metal tip plug at .35 and have not had issues. Or go to the HEI cap conversion and use a remote oil filled coil.

Hi Kid.

I have been running an MSD billet distributor and a MSD Blaster 2 coil in my 56 since 1998. In 2012 I added the MSD 6AL box. I have not had any problems at all. I sure love the 6AL box. Wow what a difference. I used to foul plugs if I wasn't careful starting the engine, but not now. It runs so much smoother now.

I am running it on a 383 stroker with dual quads and all roller.

hope that helps.

I run an MSD Digital 6 box and MSD HVC-2 coil, no issues here.

Perhaps a continuity test or a ground test will help provide an answer.

I've found a few coil problems for friends in the past by discovering a ground fault at some point that had been overlooked.

Or maybe as remedial as it sounds, the coil was possibly sitting directly ON the hot intake manifold? They need an air gap. my .02

that's a good thought about grounding. MSD need a very good ground. If a problem seems to come and go it sounds like a grounding fault problem. Ask me how I know this!!
