Chnaging plug wires on an LT1 is a real pain. It could take anywhere from 2 to 10 hours.
Don't be afraid to remove stuff that is in the way, like alt and starter.
Cheap wires are NOT the way to go; I like MSD, but another great option is the Thunder over the valve cover kit. Using the stock brackets is important, unless you want to replace burned wires frequently. There is a reason the #7 goes all the way to the back of the block and back to the plug.
Wires MUST be secured against any contact with the manifold/headers. If you skip this or 'just use regular separators' you'll be doing it all over again soon.
FWIW, I believe the Mitchell's guide calls for somewhere between 4 and 6 hours.

Jeg's Pow'r Wires $29.99 I actually bought a set of those and MSD 8.5mm S/C. The Jeg's brand are my backup set of wires. They are a bit of a pain. Take your time with them. It'll be an experience, if it's a pleasent one, that's up to you.

I put on some stock replacement ones from Advanced for my car. I looked everything over carefully to make sure none were touching the headers. I refuse to use the thunder racing kit and will NEVER reccomend it to anyone. I will NEVER custom make a set of those wires ever again. They are absolute crap.

The problem that I have found with the MSD SC wire are the Spark Plug boots are a little too thick or at least in my case. I am running block hugger headers and I had to replace them after my second trip out. FWIW the Taylor wires are pretty nice and this time I routed them over the headers. It looks nice and seems to be working well.

Since you have headers get some wrap for your wires especially if there not coated. Also I really like my MSD 8.5 SC wires. Also what plugs are you running? If your running a a stock plug you might want to switch to a NGK TR55 the overall length of the plug is shorter and helps with clearance.

Launching!
I did mine for the first time on an LT1 in an fbody, yesterday, and man what a PITA! Took about 6 hours or so I think. I could definitely do them quicker next time. I can give some suggestions based off my experience of doing them once, so take it for what its worth.
1. Remove the alternator.
2. Do cylinder 1,3,5, and 7 from the bottom.
3. Do cylinders 2,4, and 6 from the top. With the alternator removed, this is possible and much easier than doing it with the alternator in place.
4. Do cylinder 8 from the bottom.
5. A 15-18" breaker bar with a swivel head is VERY useful. I'm not sure I'd be done yet if I didn't have that tool.
That's what I learned the first time out. I would guess it would take about 2 hours if I had to do it again. I used a standard 3/8" drive, a spark plug socket, a 3 inch 3/8" extension, and the breaker bar I mentioned. (of course other tools to remove the alternator) For me, it was time very well spent. Whoever had this car before me wasn't the most intelligent person in the world, and that's being nice. This 95 bird is a project car for me, and most of what I've worked on so far is undoing or fixing things the previous owners did wrong. (or who they had work on it). Some examples, cylinder 8's spark plug was half threaded. 2 other plugs were not tight. Cylinder 8's plug wire was the OEM stock plug wire. Obviously someone decided it was just too hard. I will admit, cylinder 8 was a pain. I would say, this is the toughest car I've ever changed plugs and wires on. I was physically worn out from just doing this job.

It took me 8 to 10 hours the 1st time I changed the plugs and wires. It was a real pain to do so I would suggest using good wires when you do it. I made the mistake of cheaper wires and had to do it again. I used MSD super conductors and boot protectors the last time and took my time doing them. Routing is very important as well as zip ties came in handy! Just know it will be tough the 1st time and have some patience!
