Which Harmonic Balancer?

I'm assembling a 407 internal balance SBC.

I want an SFI approved model, but which one?

I've seen ATI, TCI, and Fluidamper all with their own designs...

Any pros and cons to which one since they are all similarly priced?

Also it is for a 69 Nova so...

Thanks

:)

ATI was my first choice. I live ~25 miles from ATI in Baltimore.

I like Fluidampner as absent of wear parts. No rubber to rot out. Silicone does the dampening and only thing to wear is contact area with timing cover seal – repair sleeves for that. Use’m engine after engine. Have read the fluid ones actually reduce timing chain vibration/oscillations for more accurate valve timing – and less horsepower losses. The Street Dampner price wasn’t much more than a stock piece but had to paint it and not SFI. :thumbs:

FluidMaster Dampener.
I use a street dampener. But they also have the SFI Approved.
Good Luck.
Look at jegs web site.

I've always been partial to Fluidampers...no experience, but what I have read in the magazines.

My engine shop said they see the fluid turn to jelly over a period of time. Machine shops don't know everything, but I certainly don't either...

I'm leaning toward the Fluidamper though-figure the o-rings of the ATI could wear out in a few years just as easy...not sure about the Rattler...does it rattle? Does anyone know? :)

Thanks for the input. More parts to buy...

No Go, i've got a Fluidampr on my 350 (internal balance) and might be selling it shortly if your interested. I'm installing a external 406 over the winter and will need a weighted balancer. Let me know if you're interested.

Another source you may want to consider is Speedway Motors in Lincoln Nebraska. They have chrome plated, SFI certified, degreed dampeners available in 8" for the 400 ($144.95) and 6.25" ($139.95). The picture of the dampener on the Speedway website looks just like the picture of the one on ebay. The cost is about the same as the FluidDamper non-certified StreetDamper.
