I have a 235 engine with a casting number 3836233. On this site, I was told that this is out of a 55 sedan delivery, full pressure. (0309I48F55Z) :rolleyes: My question is, when did the babbit engine become obsolete? Someone asked me and I did not know the answer. They kept telling me mine had babbits and I believe they are wrong. You guys know more about this than I do. Thanks.
