I like the taylor over the valve cover wires. No worries of burning them, they perform great and they look nice in your engine bay.

I had a hard time routing my MSD 8.5's around the front pass side of the engine in back of the ps pump. The wires are too thick to fit into the holder there. My next set of wires will be no larger than 8mm.

Do the over the valve cover wires work on a car with stock manifolds or only ones with headers?

Stock manifolds use the factory routing, if you have headers you can use otvc wires.

I went with MSD 8.5s for my OTVC set up, here's a pic:





I like the MSDs because the Opti terminals have a very "positive" feel when they snap on to the cap so you know they are on there good. The wires also have a lot of heft to them.

I've got OE manifolds and OE wire looms. I've been using Moroso Blue Max wires for the last 7-8 years. Good fit and correct length, no problems.

Yeah, they were cut-to-fit. Also, the Made-For-You looms are meant for 8mm wires but they still worked pretty good with the MSDs, just a tight fit.

Most of the big name manufacturer are all good. Taylor, MSD, Accel, Moroso just to name a few. And they have the correct length for the LT1's.

Personally, the over the valve cover set up never really impressed me, it just makes the engine bay more cluttered looking with more wires in view. Just my opinion. I use Taylor spiropro myself in stock location. Here's a pic which I think is a cleaner looking vs. otvc set up.

those are some clean looking LT1 engines/engine bays.

One mistake that I amde was buying MSD 8.5 wires and placing them in factory looms beehind the A/C compressor (drivers side wires did not go back through wire looms). This pinched the wires and the car ran like *** until I found the problem. I checked everything and the passenger side of engine always showed different readings compared to drivers side when scanning. Looked for exhaust leaks, vacuum leajks, etc, etc, just anything that would make that side of engine read differently.

I decided to try some $45 Oreilleys 7 MM plug wires (Magna Sparks, Dura Sparks or something like that, LOL) and when I fired the engine with the new plug wires it sounded mean as hell and after a few blips of the throttle, I could tell I found the problem.

A quick trip around the block and GOOD GOD, the car ran like it should have ran when it was first put together and after chasing problems for 2 months, this was the one thing that made a difference.

Those cheapo wires are still on to this day and the damaged MAD wires went in the trash ($100 lesson learned the hard way).

ANYWAY . . . . . just make sure and enlarge the factory wire looms if using larger wires so you do not make the same mistake I did.

Just an FYI, the Moroso wires that I used fit through the OE looms, etc...
