Looking for a race quality non fluid dampener

Just wondering. Why not a Fluidamper? If your engine is a 70 and later aluminum pump. A 69 and earlier lower pulley aligns with with all the pulleys and it under drives .

That is what was recommended when I bought the Damper years ago. Spin that thing up to extreme RPM's. and SmOOOOth . I wouldn't run anything else on our bb and sb race engines.

From what I was told the floating ring also catches up so less initial reciprocating weight.
