Dennis; here are some shots of a local 57 T-Bird. This car was purchased new here in Denver at Skyland Ford. Skyland Ford was a racing dealership and sold cars that they had customized before selling to new car buyers.
These valve covers are a curiosity around here. They say “Dragster Supercharged” on them. The owner says that there are no marks on the inside.
This Bird is an original “D” code car. I checked the ID plate. The valve covers could have been installed at the dealereship. Can we shed some light on these valve covers?
Skyland Ford sponsored the famous Kenz and Leslie Streamliner. World record holder in 1957.
Cheers, Ronnie
