I will post my engine experience so other early babbitt owners may have some references. I own a 1929 DeSoto and the engine is babbitt poured bearings. There isn't a lot of info out there on these engines, or a lot of help. The knowledge is limited on my normal forums ( yes this includes the NDC and here) on the babbitt engines. I am so grateful for the help that I received on my 49 Chrysler so I will try to return the info I get on my 29. I will post pictures as this process develops. I have already sent my crank out to be turned. I have found info to help from a Facebook group for flathead 6s and of course the Jalopy journal (hamb). There are a couple others but those two have helped a bit. I will be back with pics tomorrow.
