340 K Member ??

Well, to add my three cents. My 71 340 Demon GSS has the washer, the K frame from the other 71 Demon 340 I parted out has it and it looks like this 70 Swinger that I just sold also has the washer. If you look at the pic it looks like you can just see the top of the washer. I think I remember seeing it when I took the pics.

Now, I'm pretty sure my 68 340 GTS does NOT have the washer. I think only one person here said they had a 69 340 car WITH the washer. That makes it seem that at some point late 69 they started doing this.
I'd like to see a comparison between the 318 and 340 k frames to see if there was any "beefing up" done to them. I never noticed any differences.
I can contribute at some point by taking better pics of the 340 K frame I have for sale.
My guess, the washer just meant the assembly was for a 340 car so the builders knew what to install coming down the line.
