That they did and continued to use it for years, the V-2-34 engine is based on the V12 Hispano-Suiza aero diesel and here's the oddity, there is a stroke difference of 6.7mm between the two banks of six cylinders.

The left bank has 180mm and the right 186.7mm with respectively 14:1 and 15:1 CRs. There is a good mechanical/geometrical reason for this, especially with the aero heritage and I was sent off on a quest to find out why someone would make such an apparently unbalanced engine. Interesting it was, anyone take a guess why?
