Bill --
Thanks for the info. I'll see what I can find out from Erhenberg as I think he does know quite a bit about the old MoPars -- at least he did a good job of explaining ram induction when the mag did an article on my SonoRamic Commando-equipped '60 Fury.
BTW, the only external engine identifiers (or "scare emblems" as we used to call them) on either the '65 I have now or the one I had back in 1964-67 are the "Commando Power" V on the front of the fenders and the "426" hood ornament. Now, my '60 Fury has a big chrome horizontal bar with "SonoRamic Commando" intersecting a swept gold "V" with "Power" on it.
