Call March pulleys, they probally have a custom aluminum one for that application Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

I had one on a 440 and had to hone it a bit as it was too tight (may because of swelling from having crank hardened) Then I thought I'll save $5 and use it on my KB crank for a 542. well it went on really easy. (could tap it on with a big rubber hammer??) well it started to rattle and worked itself oblong before welding itself to the crank and braking every main web out of the engine and the crank then in 3 pieces!! RIP 542. I have a new fluid on my 452 and it stays there when I start my next 542 project!!

I won't run them. , nothing but bearing problems when i ran one, my bearings after 60 passes were all smeared, i raced the beaerings, same thing again. i went to a ATI super balancer and no more wiped bearings. they are junk for any decent HP motor.

A lot of the 500 C.I.Pro Stockers ran them for years They didn't race in the cold either Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Quicktree,i remember reading one of Eddie's posts with something to that effect. keep in mind those are mid to high to mid to high to mid, etc, etc. high rpm SBC motors with the tiny little snouts on them. IMO, that's not a good environment for any fluid type dampener, regardless of brand. also note that fluid dampers are much heavier typically than the ATI, Romac, BHJ, etc. etc. that heavy rotational inertia could have something to do with the problem Eddie had. those dampers aren't normally my first choice, but so far, every one i've used (probably over 100 of them) has worked just fine.

I talked to an old-hand Nascar hemi builder who said that their testing revealed a 25 hp gain, BHJ over Fluidamper,on the dyno and the engines smoothed out. Fluid dampers are heavy. Maybe tuning for extended, consistent rpm ranges has a bearing?

The damper is for torsional vibrations, it has nothing to do with the balance of the motor. Elastic type dampers will work best at a certain frequency of vibration and the effect will diminish the farther you get from that number. I expect that the viscous (fluid) type dampers will be effective over a wider range of engine speeds.
