Björn Flodén and his wife built one of the first BD-4s back in the 70s. When
they moved to Colorado he wanted more power and installed a Ford V-8. He
never got it in the air, though, as he passed away before completion. His
daughter wants to sell his project now. While the BD-4 builders help out
with information about the airframe, we know little about this engine. Who
could provide some background information about this monster? Has it been
used by others?

This is a page describing the project:
