Fellows,
At once a friend of mine installed a 350 chevy damper on a 250. Required some machining to the part, but as long as the inertia ring was not subject to the effort of pulling water pump, a/c p/s etc... we both imagined it would be a nice feature, and a longer damper life once the engine was meant to rev high. Been browsing the Leo Santucci book and found no reference on it, what do You say, Fellows?
