Quick question, as I don't have the assembly manuals for 68s - do the spark plug wires route the same way on a 68 GT350 as they do on a 67 GT350 (e.g., the #5 plug wire on a 67 GT350 routes under the #8 & #6 wires on the driver's side)? A picture would be fantastic, if possible.
Many thanks in advance! :D

Yes. That is the factory configuration . FYI the reality is that the possibility of spark induction misfire (reason for routing) if the wires are routed parallel to each other (5,6,7,8) is extremely remote
Outstanding - thanks, Bob!
*Beer Emoji*...if we had one
Another more obscure detail is how do the plug wires route around the thermactor tubes on a '68 GT350 with T/E? I haven't been able to find any good references for this.

I miss that one too. ;D
Maybe that's why Kopec asked me if I was drunk after reading my posts? ::)

Look in Bob Mannel's Ford small block engine book. There is at least one excellent picture of the wire routing on a 68 302 with thermactor. The only difference between the picture and your configuration is the valve covers. Wires should still be routed the same was as production 302s with thermactor.

Outstanding point! I have that book and didn't even see the picture you mentioned until now. I think you're referencing the one on page 8-22.
Thanks!
Page 8-40 and 8-48 show details. The LH side wasn't really the question, although following the pics, the #8 wire is laying against the smog valve. The RH side wires mounted through a clip in the middle of the Cobra valve cover, not like the ordinary 302 with the stand-off bracket. I'll have to see if the plug wires fit with all routing behind the emission valve. Right now, I believe I have them split, 2 in front and 2 in back.

Did you find you one of those white wire separators/holders?

There is an off-white wire separator on one side :)
It would be helpful to those that do not have that book to post some scans or pictures?

Any early Mustang/Shelby enthusiast ought to have a copy in their reference library: www.fordsmallblock.com

At the same time IMHO we need to respect peoples work, time, effort and copywrite
Just a thought
