427 Block help

[Woodz428]

If I am not mistaken, all service blocks were also machined for hydraulic lifters. They came with block off plugs/pins but were easily converted. Most likely because the '68 427 was a hydraulic engine.
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.

It was in the date code. It was in the place of what should have been the year code. The month and day code were regular numbers, it was only the year code that was odd. I've never seen the Omega sign used and since I know it was a factory service shortblock ( not cap screw rods) I assumed it to be used in service blocks...but that is just a guess.

Thanks everyone. I will post picks next week.

Any idea of value? We want to sell it.

Are you sure it's not a 0 with 2 dots underneath? Gotta pic?

I have pics, I documented it for the owner. It was definitely an Omega. I looked at it with a magnifying glass as did several others...Omega...definetly. Living in a College town for decades I saw many,LOL. I'll see if I can't locate the pics and post one. It's not relevant to the value of the engine( it had been grenaded, and repaired...including a chunk from the block skirt that wasn't up to containing a rod), but the oddity drives my curiousity.

I'd like to see those pics of the Omega. Here is a pic I found interesting....a dove stamped on the oil pan face of a 1965 HM block, just adjacent to the front main cap. This was a C5AE-G block, dated Jan 8, 1965.
