Question on spark plug wires on a 350 routing. Did the stock configuration route out the back and then up the side? A set I got at a local parts store doesnt have enough long wires to do this. Some have to be routed across the manifold and over the valve covers to get to the passenger side. If the factory configuration was down the back and up the side, does anyone sell a set that works for this?

 

One option is going to summit racing or jegs and order a performance wire set that you can assemble yourself to length.

 

Over the back top half of the valve cover, not between the back end of the valve cover and the firewall.
