Turned out I lost the rubber out of my balancer, which had been rebuilt about 10 years back. Guess I turned 4,500 rpm one too many times. I have located a used balancer locally, will go pick it up tomorrow night. Guess if I have to go anywhere tomorrow I will have to ride a bike!

It's my opinion having a damper rebuilt by those guys may not be the answer.The original rubber discs were a certain density tuned for a certain RPM.Is there anyway of knowing the silicone rubber used in rebuilding is tuned properly? | | |

Had about 20,000 miles on the rebuild. The rubber is gone. Haven't pulled it yet, will do that when it quits raining. Here's a pic. http://www.myoldtruck.com/gallery/files/2/3/8/damper.jpg

Performance dampers,ATI,Fluiddamper small block models will fit with some mods,but the pulley situation and damper size is a problem,no room otherwords. | | |

I checked the water pump and alternator, but they both turn freely.

Engine idles nice and smooth, as near as I can tell. I'm not too worried about it, since my driving is down to about a tank of gas a month and I don't have get in the 70 mph rat race to go to work anymore.
