I am installing the Holley Sniper EFI on my 1972 Blazer and was wondering if any of you have installed this system on your Blazer. I am having trouble finding mounting locations for the coil and the Ignition box. Any suggestions will be appreciated.

yes it is
In my 89 I mounted the ignition box on the driver fender and the coil is on the firewall just below where the hood ends up when closed.
You may consider the CDI on the inner fender as mentioned, the build a bracket to mount the coil off the intake like originally done with the points set up
If he has the ignition box, he probably has the square e-type looking coil that plugs right into it. For the life of me I can't find installed pictures of mine anywhere.
Wasn’t sure, the other injection systems say not to use those coils
Exactly the sniper coil is square and is huge so no clue where to mount it
For what it's worth, here's where I mounted mine on the firewall.
I’m thinking about mounting it on the other side by the brake booster
Heat is always hard on electronics, I'm surprised no one is putting this stuff inside somewhere.
So not helpful on the Blazer but I did a sniper setup on my Chevelle. I went with a canister style coil in the factory location on the intake and a coil driver hidden in the plastic gutter channel that runs along the fire wall. Looks stock, runs fantastic.

I know it says somewhere that you don’t need a return line, but for my 77 gmc, I’m going to install the in take pumps, that will increase the fuel pressure and cool down the fuel as well, to get the most performance possible. It’s a spendy and time consuming adventure but after extensive research this is the best result for fuel delivery.
That’s what i did in my Chevelle too. I learned that when you run their drop in pump you might get fuel knock (like water knock in your house) and it makes the sniper think your fuel pressure is all over the board. I was getting nasty lean spikes. I installed a fuel pressure damper from Radium Engineering and it’s been working great. It took me a long time to figure it out so wanted to share the info!
Here are a few of mine, I hope to be done in the next couple of weeks. Wiring is a mess, still have to get that cleaned up, hidden where can and secured. This should give you the general idea of where I am heading…
I think I about have it completed
This is all optional right? You can just run the HEI and vacuum advance distributor with the sniper controlling fuel/air, no?
Edit: the only one I’ve got experience with is their Jeep 258 single barrel kit, on a friends, works great with no timing control.

I have the hyper spark distributor so I can control the timing
