Coil behind firewall

[RoadRage]

Has anyone installed their coil behind the firewall with a pass thru to distributor? If so, did you experience any downside issues?

I have. I mounted the coil using vibration resistance mounts (rubber) to the cowl (wiper linkage area) in my '66 GTO. I used the MSD bulkhead pass-thru on the firewall, and made 2 coil wires. One from the coil to the bulkhead and one from the engine side of the bulkhead to the distributor. I haven't run the car that much yet, but both in practical experience as well as having talked to MSD - no issues whatsoever. My ignition is already in my glove box, which makes it even easier.

Excellent. Thanks for the feedback.

I had it that way in my 67 Nova David, no problems

I did all all igniton components bolted to a single panel
behind glove box door on my last 2nd gen Camaro.
It worked fine.

Did anyone have trouble with a stereo installed? I would think that ignition noise would be an issue.

Stereo? In my car, I don't think you could tell. You can't hear the stereo with the car running anyway

Seriously, it could be an issue. I'm running shielded cabling from the MSD 6AL2 to the distributor. I'm also using a Secret Audio mounted in the back of the car. So, can't tell from my perspective.

I have my Msd box and coil mounted mounted behind the glove box also. Anytime you can keep your ignition box and coil cool thats a good thing.

Do you have a stereo, nav equipment or electronic gauges mounted in the dash? If so, does your coil cause any interference with this equipment?

[wmhjr]

I have all Autometer electric gauges in the dash. Zero issues from the coil or ignition.

Which plug wires are your running? My Autometer speedo is going nuts over what I believe is ignition interference.
