I didn’t ask that question and now I wondering why. Do you mean another brand like a MSD Blaster or the Ford coils he was selling?

MSD or Mallory, Accel, Most aftermarket coils will support enough voltage for an HEI. The coil you have will work but it's not mounted as you would have wanted.

I may consider changing it out in the future as I would like to mimic the factory look.

11/20/22: Today, I sand blasted my twin horns I acquired from a fellow Stovebolter. I love this forum, as l have obtained many needed parts for our truck, thru this forum and I have to thank those who have helped.

A little bit of satin black spray paint and there ready for installation.

Were those optional horns? I thought the ADs all got the single horn mounted on the exhaust manifold.

Where do those mount?

Fire wall above starter
Most of my trucks have two horns in that location
Might be a Canadian thing,
Also some Canadian gmc have one on manifold and the second is alone up on the fire wall
Likely it was a new requirement at about that time and a late factory addition/modification
When the truck has two horns they are hi/low notes just like the modern horns today.
There is a special bracket for the dual fire wall horns
Also when a truck gets two horns it got a factory horn relay installed next to the tiny fuse box on the fire wall
GM did not try grounding out two horns in the steering wheel.

The horn part is pot metal but the dome is pressed steel. I first bead blasted them then used my favorite spray paint, Ace Hardware Premium Satin Black. Covers in two coats, built in primer and drys fast.

12/09/22: I installed my horns today. After much debating, primarily with myself, with the input from our fellow ‘bolters, I decided to hook them up in series. I bought rivet nuts and a new installation tool to install in the firewall, printed a insulating spacer on my 3d printer and bought 1/4”-20 nylon bolts and washers. I had previously wired the two 6v horns wired in series on the bench to see if it would work and they did, so I was all set to do the install.

Unfortunately, my plan fell apart when I tested the install. Only the high toned horn worked. The low didn’t even make a click. I was baffled. I retested each horn separately on 12 volts and both worked, loud but did work. I tried adjusting the low toned horn while in series but to no avail. I tried feeding the low first then the high (opposite to the way it was), again no joy.

At this point, I decided after spending way too much time testing different ways to install these horns, to run them in parallel as was suggested earlier in another thread. After changing the wiring and reinstalling the horns, I retested the horns and they worked! Unfortunately, only for a couple of seconds. My first thought was I burnt them out, but then decided maybe it was just a blown fuse. Turns out when I originally install the horn relay, I installed an in line fuse which was only 10 amps which blew quickly trying to power twin higher amperage horns. I installed a 20 amp fuse and so far it’s good. Both horns work, a bit loud but sure to get attention. After all, isn’t that what horns are for?

Horns should be loud, especially when you are istening to them with the hood open and the engine not running. Imagine being in a different vehicle , several feet away with the windows closed and the engine running and probably radio blasting.
