I spoke to GEP recently about the imported blocks. I was told that aftermarket cylinder blocks cannot legally use identification marks such as GM, AMG, GEP, Navistar or even the 506 casting number. They are aware of the heads & blocks, and have evaluated them (cut them up to look at casting qualities and alloys). They wouldn't comment on them further.
By the way.... the forged-steel cranks are almost here....

Thanks!
When identifying these blocks, what would the date 0206N be? How do I break these numbers down? I thought the N was a month, but that would make M the last month. Any help?
I tried to look up julian dates, but the numbers used on engines isn't true julian numbers. The letters used are not in the julian system so this must be some bastardized version used by the manufacturers. I still can't find out what 0206N means. It is in the right place on the block. I simply want to know if this is an 06 engine.
Date codes switched to a different format in in 2001, you can find the info for both formats in the following thread:
