Related to SB & BB Chevies the internally balanced have all the required counterweight on the crank & thus the balancer & flywheel are neutral balanced. Externally balanced (OEM SB 400 & BB 454) do not have enough counterweight on the crank & so some has to be put on the flywheel & balancer to bring the assembly into balance. |
