Hi Rich and all, Batwing is not what Chrysler referred to them as. Everything I've heard and read states "DeltaWing". They were built by Delco for Cad, Packard, Chevy, DeSoto and Chrysler. Don't know about all of the others, but the Chrysler units are unique to themselves and will not interchange with the other cars. Also Chrysler is the only one that have the ribs running fore and aft. Caddy did have a large chrome V on them and used hold down knobs that looked just like they were off the kitchen cabinets. The Packard examples were mounted on the carbs 180 degrees from the Chrysler and look rather strange with the V or point going towards the firewall. Sometime back I wrote an article that was published by the Chrysler 300 Club International detailing some of this info. Currently can't remember what issue that was.

I understand the batwing was manufactured by Delco for Cads, Chryslers and some other car (perhaps a T-Bird?). Note the fancier fasteners holding the oil bath pots. Additionally, the Cad batwing appears to have a Cadillac "Vee" on top and does not appear to be interchangeable with those on the 1955-56 Chrysler 300's. According to Hemmings, the Eldorado could be had for 54% more cash than a Chrysler 300B. I drove a '56 Eldorado once and it performed very poorly due to the Rochester carb secondaries getting clogged up from lack of use by the little old lady that owned it. I was happy to blow the cobwebs out of it for her from time to time. I was not in contact with the owner of the only 1955 C-300 in Des Moines, but would have been happy to provide this service to him. I visited that same Chrysler 300 this summer in Iowa, where it has sat outside too long and developed serious rot in floors and door posts. I love that old car, but decided it was too much to bite off to restore it and find an engine for it.
