1968 327 CE block engine code

[WSSix]

My friend recently acquired a 327 that we know is a Chevrolet Engine or crate engine from 1968 given that it has stamping CE839012 on the front pad. What's a little confusing to us is the date stamping which has the engine option code. It's stamped V0109HT. We know this is an engine built in Flint, Michigan on January 9th. I can't find any information stating that HT is indeed the same 350hp 327/4 speed engine that was available in a 68 Corvette that would have carried the HT stamp. Can anyone confirm that the engine code was the same for a crate engine as it would have been for the production engine? Have a source too possibly?

For the record, the block and heads carry the correct stamping/casting for a 350/327 or L79 engine as it's called. I'm fairly certain that HT does mean it's the same L79 from a Corvette. I just can't find any confirmation of that information.

Thank you
