1968 327 CE block engine code

[WSSix]

Thanks guys. I figured I might need to try a more restoration oriented site but wanted to post here as well.

As for CE. I read that it's officially Chevrolet Engine, versus Pontiac Engine or Oldsmobile Engine for instance which were also available as crate engines, but that through the years people have also called is counter engine, counter exchange, or crate engine. Honestly, that's not in question. It's the engine code HT that I'm unsure of since it's a CE block.

Thanks
