I would only have a start for concern once the 475 to 500 hp level was being reached.
The core of the crank where it counts in terms of strength is still the same, as in from a main or rod journal to the crank cheek.
Plus with a 3.750” stroke the rod fillets are seeing 12.5% less G force then if the motor was a 455.
