I almost bought that boat a while back when the original owner was selling it. I'm pretty sure it had a 454 in it originally.

yes it did, and still does. It’s been gone through and now has a custom cam, intake and aluminum heads. Ran mid 90s with a blower and now runs low 70s n/a for now. I’d like to get 1 full season out of the current setup and start putting together a 540
