I'm bringing over a thread started in the 'Welcome Wagon' section on Budnicks (thank you) suggestion.
I had a chance to start working on the Hemi this weekend. I photographed all the various stampings on the block, and I appreciate any help you all can provide as to exactly what they mean. The first couple pics are the stampings just below the starter. I know the 'NM' is likely stamped backwards and should mean the plant where the motor was assembled. '426' is the cu. in. of the engine and the next four are the date code. However, I couldn't find how to decode the date code. Can anyone help with that? Also, what are the number following the date code? The next pic is the machined pad on the passenger side of the motor. Is this a partial VIN? The next two (2) pics are of the camshaft. I read on one of the forums that camonics did some custom grinds for Ed Pink, but I really don't know if this is a custom grind or not. The next pic is of the crankshaft and a date stamping of 4-17-78. This motor was built by Ed Pink in 1978 so I assume that this date stamp was done during that build. Beside the date stamp is a KC and an M with a circle around it. Is there any significance to those markings? The last pic is the machined pad on top of the motor. It is stamped 'WT' which I understand all the Hemi's were and meant water tested. Any information that can be provided about any of these stampings would be greatly appreciated. Thank you all in advance!
