A 348 or 409 crank can be fitted to a big block for a shorter stroke. There was a big block 68-70 Nova running in D/gas at the National Trail Raceway in Columbus Ohio spring NHRA points meet in 1972.

Yenko Performance and Marine was selling aluminum blocks in the 1970s and 1980s. There was a few different blocks sold in different configurations. Some were "dry" blocks and some had water jackets like the iron blocks.
The Yenko blocks were used in drag cars, road racing, boats, Sprint Cars and others. I'm not sure what that block was used in but maybe was something that ran alcohol fuel injection as I have seen some of them running "dry" blocks or a boat application that ran an external heat exchange cooling system
