Guscha,
I really enjoyed reading your post (as always) and have long wondered about the Cummins connection. Allow me to explain... I have an antique Mack semi tractor with a Cummins diesel. A while back when doing work to my 320 Packard engine I realized there were many similarities. The side mounted roller rockers, the oil distribution and delivery system and the general design made me wonder what the deal was. I called a friend that is much more versed in the history of Cummins than I (he worked for Cummins many years ago) and asked if he new of any connection. Without any hesitation, he said it seemed Cummins had interest in the Packard engine design and knew of the diesel development around that time. My friend considers the connection and similarities in fundamental engine design to be more than coincidence. While I have no real idea either way, I would be most interested to hear what others may think.
