Do I need to have my rotating assembly balanced?

What can you stroke a 454 to?
Take a 454, add a 4.250-inch stroke crank along with some 6.385-inch rods and your displacement shoots up to 489 cubes.
What is the bore and stroke of a Chevy 454?

How much does it cost to balance a rotating assembly?
As for the cost, most balance jobs price in at around $200 and typically take up to two hours to complete—of course, this is assuming everything checks out clean. If weight has to be added for a perfect balance, you can expect the price and the amount of time it takes to get the job done to go up accordingly.

How far is a 454 bored?
They can safely be bored to 4.500 inches, which, even with the stock 454/502’s 4-inch-stroke crank, yields a displacement of 509 ci.
What happens if an engine is unbalanced?
Unbalance in elements of the engine can also lead to severe vibration. Tension in the belt as well as an increase in vibration are one of the main causes of motor failure. This in turn will reduce the scopes of vibrations in all the operating systems.
