I like this layout. Raw, yet very squared away.
My only adds would be covering the wiring in expandable sleeving and some stainless allen head hold down bolts. Overthinking this? Lol..

I love the look of that modern harness wrap that looks like black cloth. I'm far too lazy to go through it all though.

The cloth stuff you mean Tesa tape? I would not use that in the engine bay, it is like yarn. I presume flammable and moisture holding. The heat version is good for engine bay but you'd be wrapping forever. There are numerous options out there for lengths of loom to get which can clean it up. If you're going to readjust the harness for length and lay thata chore, but if you're just shesthing it to clean it up you can zip the bundled sections quickly with a thicker loom, go back and do the short sections another time with thinner. But agreed, not necessary.

Would love to see some concrete evidence these actually do anything. Maybe what your replacing them with is actually inferior? Guess it would have to be some sort of dyno test back to back for actual proof?

As far as which are better? Perhaps the question should be which coil works best with a particular ECU. Or…which coil works OK with a given ECU, and also looks cool. I vote for the latter. 👍

Correct! Never meant they were better or worse. Just that they were on sale CHEAP!!

That to me looks ****, do the Proform covers come with the coil brackets? What plug wires did you use, because the ones on my stock setup coils/covers would be too short I think.

I used the Firecore truck wires which are a touch longer than the stock wires. Here

You can get mounts from Proform for both the LS1/6 style coil or the LS7 or truck style coil.
