yup looks like it was a good time to take it apart and fresh it up
the number 91170 on the pan rail i'm not familiar with, seen them before in pics but IDK exactly what the number in that location represents? odd that if taken literally as a date September 11, 1970 that predates the cylinder head casting dates by about 10 days - 2 weeks. i wonder if it could be a cylinder block machining date?
nothing hand stamped in the front face of the block near the timing pointer?
what's the refresh plan?
