Item as described great price.
They are great wires. I had an old set that were melted next to the headers and just replaced with another set of MSD.

Great upgrade!
Not only were the MSD wires easy to install but the more than appropriate length of material to work with was so beneficial. Measuring around the the headers was the significant task and with more than enough length to work with completed this quite easily. I had never custom measured and cut spark plug wires in the past but the easy instruction and accompanied MSD crimping tool made it so simple, even I, a monkey could do it.

Wires are too short
These seem like good quality wires. My #1 complaint is that the shortest wire in the box is too short to reach my closest spark plug, I had to use a Jegs plug wire in this location. Now I have mismatched plug wires. Issue #2 the coil wire is female on both ends. This would not work with my MSD Blaster coil. Complaint #3 is that the boot at the spark plug end is too large to allow my 1200 degree heat shields to fit over the boot.Complaint #4 no dielectric included.

MSD makes a great product that you said would fit...it doesn't.
You promised that the MSD Ignition wires would fit on a 1994 Corvette LT-1 engine and you got it here fast...but seems like you might have cross referenced the companion order of the MSD LT-1 distributor cap and rotor (an Opti-spark replacement for an LT-1 and not a conventional distributor for which the 31249 set you sent may well be suited). The MSD Performance website guided me to set pn 32179.

What an awesome set of wires
What an awesome set of wires! I wish that I would have purchased sooner. Seem to unleash quite a bit of power in my truck. The look of them is really clean and gives you a hot rod-style look and feel
