first off the damper dose not balance a 350, that is done internaly, a 400 is x ternaly balanced. all it dose is dampen harmonic vibration and help's keep the motor from shaking to death.
i always use the bigest one that will fit the motor with the alt and such on it in the car.
most, not all, but most 350's use the 8" but i have seen the 7" and 6" on them too.
