I bought a CSI unit out of a MOPAR mag. Real close to that price. Probably the same part. If it's SFI approved you should be fine. If you've never done one I suggest that you use an installation tool and heat it up in your oven prior to install.

A ATI dampner is not fluid filled. ATI is what I aould buy if it was my money.

FluidDampner is now out of business.

Its a C.A.T. part, as most RACEPARTS are. I had one on my 340 and it was well built, but heavy! Although it says it only sees 2/3 the weight, it was still heavy, and your crank bolt will NOT fit the fatter damper, it is too short, you must get a longer one. Also, your belts will not line up either. So you need a custom pulley, or shim out all the accessory pulleys. Now they make a B/RB damper that has the correct pulley mounting position, but it is the "new and improved" model and must be specified when ordering. It is SFI approved.

PISHTA, what does C.A.T. stand for? Also thanks for the tip on this damper. which damper do you recomend?

499X,you say ATI, is this what you have? Is this a straight bolt on with no problems ? Great product?

thanks

My Crank Bolt and pulleys lined up fine. I'll try to find the exact one that I purchased.

I don't recomend them at all if you have a little cooler climate and if your engine is fast reving.
But on a std. typ hp engine they are fine.

So if you race when is cool wheather and your engine is a quick rever look for something else, like a rattler or like I use a BHJ aluminum damper just like they use on Nascar engines.

Don't misuderstand me the fluid will work on high reving engines but it is a bit slow when you have a real quick reving motor.

Take Care

Yes, I run a ATI on my 499. Some machinests do not like FluidDampners because they can not check the balance of them.

I guess then you are contradicting this from Fluidampr

Does the Fluidampr or Streetdampr require "warm-up" before use?
No. The silicone fluid in the damper will deliver consistent performance over the entire range of operating temperatures in any operating environment that the damper will encounter.

We in the cold Nordic enviorment have had problems with Fluidampr, one of our best engine builders have broken many cranks and has now moved over to TCI Rattler and no more problems.

At our spring races we have real cold day's, 10 deg. celcius during the day and 3-5 deg. celcius during night. I don't know what that is in farenhait, 35-40 deg. farenhait or so.

This engine builder have meet with the guy's from Fluidampr many years ago and told them the problem and they just said no way that will happen, but they would not like to try it them self to see if they where right or wrong.

I don't know, but I stopped using Fluidampr after those problems.

C.A.T is here Catpep (http://www.catpep.com/catproducts/dampers/SFIfluiddamper.htm) They make all sorts of parts for cars. Designed in USA, made in China. Some people dont like the made in china part but the dampers are built like battleships. The fit and finish are excellent and the threads are sharp and clean. The price is right too. May want to stay away from the aluminum roller rockers as someone here broke a few, but why run aluminum rockers anyway? All can break.

The tunnel ram is gone (sold on ebay). It had holley 600 vac secondary carbs on it. Ran pretty good, but I wanted everything under the hood so I've since gone to a single 1150 holley on a M1 intake.

I ordered the aftermarket dampener after I spun the factory unit. Not sure how I spun a factory harmonic???

I found a CAT dampener on ebay for my 440 last year. It fit great, the stock bolt was just fine and the pulley was exactly in the stock position. Pretty neat unit, $189 plus shipping. It is real heavy to hold, nothing like a stock unit. I really like not needing a timing tape now, too! Markings from minus 10 up to 30 then 90 and 180 and 270, and they seem to be very accurate if not perfect.

My brother had a 383 that had spun the outer ring on it's stock balancer somehow, broke the rubber or something. Devil of a time trying to use a timing light. We just timed it by ear and didn't worry about it too much. Finally noticed the outer ring wobbling a little and put another one one and BEHOLD the timing marks made sense again.

OK, someone fill me in on fluid filled dampers. CATPEP site shows one part number for 318/360, but does not list my block, which is a 78 360.
Does the fluid negate the need for the balance holes or cutouts for the externally balanced 360?
