Proper spark plug wires for supercharged C7 LT1?
Having issues determining what a sensible buy would be to replace my worn stock LT1 spark plug wires.
There seems to be no obvious choice. MSD is out because I refuse to deal with wires that are too short, as basically everyone has reported.
Anything else out there under $100?

Granatelli is the way to go when it comes to wires especially if running aftermarket headers or a supercharger. Going to cost you more than $100 but worth it. I've had the Msd and their crap and OEM insufficient with the aforementioned upgrades

My experience was the OEM melted on the dyno. Even after replacing I was experiencing misfiring. As soon as I moved to the Granatelli misfiring went away and no issues with heat.

They all work. We sell a lot of MSD and Taylor wires. The stock ones seem fine for the most part as well. I've never had MSD wires come up short though......keep in mind the LT wires area bit longer then the LS wires. So if you ordered a LS wire kit for an LT they would be tight.

I ran Accel wires on my 850rwhp CTS-V and now my 790rwhp C7. They have a ceramic boot which keeps them from burning on the headers.

I would look at speed engineering wires. I used those with my Magnuson 2650. Plenty of length and they work well with headers. Didn't need any heat sleeves around the plug wire and boot. Very reasonably priced. Check them out.
