Thought I would post this, I recently removed a 235 from my 53 truck, this engine was out of a 1956 -3 speed passenger car and indeed had a slinger in front of the crank gear when I disassembled it. This motor was a standard bore and I am the only one that has ever been inside that I could tell. I just re built a 261 from a 1962 C60 that was also never touched on the bottom end and it did not have a slinger or spacer.
