my engine block says "high perf." and has a big K next to that. i noticed it when i was changin the oil. it's right above the oil filter, ,on the driver's side. i also couldn't find any id tags or anything of the sort. i have a '68 396. is this a different block than stock? hey i rhymed!

If your block still contains the innards of the running engine, it cannot be a fake. However, the "K" blocks were sold at KMart for some years and are not really the best.

Yeah, and the High Perf (highly perforated), blocks tend to leak fluids all over, so you should sell it to me for, Oh say, $25 ?? I know how to fix them, but it's quite expensive. You really don't want to bother with it.
On a more serious note, look up the two letter code on the front of the block and that will tell you what HP rating it has. Most of the 68-69 325 horse and 350 horse BB's that I have seen have the High Perf on them. It doesn't mean much.

Gotta love it

First thing that crossed my mind was a K-Mart engine.

Seriously, if it's a big block, most of those I've seen have High Perf cast in not only the block, but the heads as well. Guess they were all considered "High Performance". There should be some letter/numbers stamped on a flat pad just in front of the passenger side head. These will tell you what the engine originally came in and when it was cast. http://www.mortec.com can give you all the casting numbers on blocks and heads for Chevy V-8s.
