Every instance where I’ve tested a fluid filled damper versus any other design has had the fluid filled dampers being down on power. That simply says that fluid filled dampers are not as effective as the other styles. I also see a much higher incidence of broken cranks in racing engines using fluid filled dampers so that’s reason enough to not use them.
Here is the link to a past thread in regards to damper testing.

From your list, the Pioneer and Professional Products dampers are good bang for the buck. These need spacers though if using standard length oil pans and not the marine timing covers. That minimizes the amount of contact area on the crank snout for the damper which could be a problem if the damper comes loose.
Although ATI does make a Y specific damper, they are pricey. So pricey in fact that I’m looking at another vendor that will make a Y specific damper. Biggest question right now is the pattern on the front for the pulleys. The two main options are the small block scrub three bolt and the SBF four bolt. Pulley selection is definitely better for the scrub pattern so I’m leaning that way unless someone knows of a vendor with a good variety of small block Ford aftermarket pulleys. Blower applications are still a consideration on the bolt pattern selection. To get the pricing where I can make it cost effective is an initial order of five. After that I’m a dealer and can get the price cut on future orders. I’m already needing three so I’m almost already there.
