Default Spark Plug Wire routing

So, I guess this is a simple question:

Do the spark plug wires REALLY have to be routed like they were stock (snaked around and sandwiched between the engine and mount)?

If not, how is everyone else running them?

Thanks,
John

Just buy regular 350 sbc plug wires and route them over the valve covers. Just make sure they dont lean on the header/manifolds!

As long as you keep them off the exhaust manifolds you'll be fine. I've seen some nice routing with hardware that run the wires from the edge of the valve cover then drop down the the plug. Most is standard Chevy supplies. But if you go that route and you buy new wires, be sure you don't get stock legnth. Stock wire sets have some longer wires to route down, under and up.

I had gone the up top route before. But after I had a shop do my engine rebuild, they routed the new wires back under the header and I've never looked back again. Even without teh old shielding, they tuck away nicely. As long as you're only replacing them no more than every few years, not an issue. Even when you replace them, no big deal just takes a little longer and a few more beers to get the job done

And it gives it a nice clean look without wires hanging all around. Out of sight, out of mind.

After removing the Air pump and pluging the holes with 1/4" ntp plugs, that was an interesting search, this is what I did. Wires are made from wire stock, but they say any top routed set should work from a GM 350 of the same year. Use the long, straight plug boots.







Everythings available from summit. I just used some standard screws and nuts to hold the holders on the valve covers.

Use the correct boots, wire length, carefully clip them together and run them under the headers....I've never burned one yet
