It's absolutely impossible to internally balance the 478 crank, I requested the balance shop to see what they could do and the end result was they put as much weight as they could to the crank but still needed a good amount of weight on the flywheel and front pulley. The only internally way to fully internally balance one is to stroke it and increase the bore, the end results would be 523 cubic inches.
