New question. For the production year 1954 I noticed in the specifications that the engine had an early production and a later production. The early production camshaft has small journals, and the late production has the same journals as the 261. I cannot locate what the specific date this change occurred. Can anyone help clear this up.
Thanks

That change actually involves "early 235" spray oiler engines, (1941-53) which ran the same cams as the 216. All the full pressure 235s I've ever worked on had the large journal cam.
