I just disassembled and documented a 427 service shortblock. The date code was an Omega sign instead of a number for the year. Does anyone know what that stands for. It was a service block with hydraulic lifter supply machined, but was sans the ribbing. I surmised that the Omega sign was a code designation used on service blocks/engines. Any opinion?

I am running a 68' SO block and now that you bring attention to the Omega sign I have some foggy recollection (the 60's) of seeing that. Can you tell me where this sign is located on your block?
My block was factory machined/cast as you describe. I found this one in good shape although it had been bored out. I sleeved all cylinders taking it back to fifteen thousandths over and chose to block off (plug) the the
oil channels, drill out the plugs, and run solid lifters, as you say the conversion was fairly straight forward.
