What would you build if limited to 372ci - with boost as an option

For a street car, or drag car, I probably wouldn't bother.
For a salt car, I would assume you would have to do anything possible for durability sake.
For this discussion, I was looking for everyone's input on what to build to get below 372ci. It isn't a deal breaker if it just doesn't make sense, but lessening a record by 20mph is huge.

Is my math right? If so, it seems doable for a displacement regulated class.
