Hey there Vette fans!
Long time no talk. Out of many subjects where I could add my 2 cents, harmonic balancers is not one of them!!
I have a very strong 327 - pushing nearly 400 ponies
and it has the stock mid-60s balancer on it. Skinny looking thing and the rubber is cracked and deteriorated. I believe it is 6 3/4 in diameter.
I have seen standard elastometer type balancers rated at 6500 rpm fpr $60. I have seen Fluidamper's "Streetdamper" for $160 from Summit. I understand that if the rotating assembly is balanced internally, then the job of this component is to absorb vibration and not balance anything. So, what's a good choice for an occasional street driven, occasional pedal mash seeing 6gs kind of fun??
As usual, thanks for your advice!!

Well I am no means a expert in the subject but I have done research on this matter before so I'll throw in my 2 cents. The stock type dampner (not Balancer) is fine for engines not going above 6000-6500 rpm so as you have described, save your money and just get the 60 doller job. I have also read in my reaserch that the larger 8" diameter dampner actually gives a little more hp (1-2 hp)through the power band because the crank shaft has more centrifugal force and has better harmonics meaning the crank isn't accelerating and deaccelerating (jerking up and down the pistons) as much. smoother rotations. But it might be better to keep the stock size dampner so you dont affect the pulleys distances and timing marks that already exist on your engine. The 8" dampner I believe is fatter so it might move your crank pulley forward and hurt your belts.
Well stated. If you are going with aftermarket, be carefull of fit and position. I also would stay with the stock, unless you can find an exact fit replacement.

Luke,
My engine builder has convinced me to go with an ATI balancer. He has full confidence in them for the chevy small block. His advise is good enough for me.
Just my 2 cents.
Thank you for serving.
