Really depends who you have balance it as prices are different from shop to shop. I had my 454 balanced and built by a local guy. My car is a factory 4-speed, rather hard to find, and uses the 153 tooth flywheel. I could have ordered the correct, 454 153 tooth one, but he balanced the stock one for the 454. He charges $80 I think for balancing, but since he put the motor together, was included in the price.
