Would it >help to chill out those burley vibes we get at 3.4K rpm? Harmonic balancers don't damp any vibrations that are noticeable. They damp vibrations that cause stress cracks in the crankshaft due to harmonics set up in the crank at idle due to power pulses from cylinder pressure ("bang!") being transmitted to the crankshaft pulley. (For a review of the power of destructive harmonics, do a net search for "Tacoma Narrows Bridge".) A balancer wouldn't change anything in how the engine behaves beyond the microscopic level.
