Best harmonic balancer??
Who makes the best harmonic balancer for a sbc that revs to 6800 rpm? I have seen a lot of cheap ones lately but I want to know if they work well. I have seen people using fluidampers or the TCI rattler and they seem good but do the cheaper ones measure up?

I just had an ATI put in mine and it is definitely a stout piece. Both my engine builder and my machine shop recommended it, and said it could rev to the moon. It also dampened a large part of the vibration I was having north of 3k rpms. The only downside is the price ($380).

I'm not biased one way or the other, the ATI is actually cheaper than the other brands, this is for a 1st gen motor, not a LT1 so the ATI balancer is only $260. I was just looking for more/other input. Right now it sounds like I should get a ATI balancer and I will probably order one tommorrow unless I get some other info. A few of my friends have reccomended TCI and a few reccomended ATI I'm just trying to get as much input as possible.
Thanks.
Thanks.

I had to have mine replaced aboout a year ago. I had an oem piece since my rebuild a few years ago. I went tith a Jegs house brand balancer that is SFI rated. I forgot the part #. So far so good.

I wondered this also, I was thinking of a 'Fluidamper' on my next rebuild, GMP markets two under part #'s 12341632 & 10051170 ones a 6.25" and the others a 7.25" and they weigh 7.9lbs and 13.4lbs respectively. I don't know if the 7.25" will fit on a C4 does anyone know?
Summit also sells them at $268 & $366. They also market a 'Streetdamper' 6.875" model which isn't SFI approved (less$$- $199) which is similar in size to the stockL98. This is what I was thinking of for my ZZ9 cammed L98, since it doesn't rev too high anyway. A m/ram or s/ram motor owner may want the extra piece of mind that SFI approval gives, I suspect it is a higher price for the label though more than anything else JMO.
Anyone have good or bad to say on these?

ATI 
If its good enough for NASCAR..its good enough for me 
I have one and when the revs get high the engine is still smooth

Balancer
I was running 8,600 rpm with a BHJ with zero issues. When we rebuilt the engine after 3 seasons the bearings looked brand new. My 406 is internally balanced which is a plus. BHJ.
