69 340-S emblem questions

That does look pretty good with both sets of call outs and emblems on it I'm sure somebody added that left-side pentastar since I don't believe any of them came that way with it on both sides. as far as the stripe goes there was a picture in this thread from a brochure that showed the 340 badging and the 340 decal now that may have been a pre-production test mule from 1968 and they obviously made changes after that

Yep, I have that brochure and made it into a PPT presentation, so I could make copies and write/highlight on pages as well as magnify images if I could, to get a better look at a certain area.

I've been slowly making a set of references in binders to have as much information as I could. I printed out 2 copies of the '69 Plymouth Service Manual (982 pages each) and so far am almost done with putting one of the copies, page by page in page protectors for 2 reasons: 1) to keep greasy fingers off the paper and 2) a dry erase or grease pencil set can be used on the plastic to write on, highlight or whatever and then erased off if needed. I also printed out the '69 barracuda collision parts book on cardstock and put in there. So far, I've got a 4" binder and may have to switch to a 5" or start putting the other references in another binder. Very, very time consuming, but hopefully it'll be worth it.

I didn't think so on the Pentastars, but I'm no expert.
