Hey man, I know you live in HV, so call Bishops Machine shop in Dallas. I don't have their number, but they are in the Yellow pages. I bought a stock HB from them last year for $30. Clean and rebuilt. They have some other engine parts also that I wasn't able to find anywhere else, including the cover for the timing gear which has the front pan seal on it.

Well what is done to your engine? If you are going over 4000rpm don't replace it with a stock one. The fluid ones are ok for racers but they have their drawbacks for a street engine. I looked into them very seriously for my build and after a year or two the fluid inside will begin to coagulate and stay in one part of the damper, no longer flowing out easily to put you in balance. In fact you will be out of balance. I was told this by a major parts house and was'nt sure I believed him so I called one of the manufacturers in Ca., can't remember who now, and they confirmed it. You are better off getting a good balancer from a reputable company. If you go past 5000rpm alot you should probably get an SFI rated one. If not there are some HD ones out there with a higher than stock rating. You can get them in chrome or black with the grooves all etched and painted if you like.

I have had a fluidamper Street Damper for several years, and have had no problem with it. Just to be sure, I emailed the tech people at Fluidamper. This is what they say.
Dan, the silicone fluid in Fluidampr used in any high performance race
or street performance engine will not solidify. The silicone fluid used
in our dampers is extremely high viscosity "or jell like" when installed
at the factory and some people try to make the user feel that it has
deteriorated over time. It will not.
The dampers we make for Series 60 Detroit Diesel must last a million
miles and we have not seen a fluid failure yet nor have we seen a fluid
failure on any performance application.
Performance applications do not work our dampers anywhere near as hard
as do diesel engines.

tasty...i'm just doing the top end...i'm in the disassembly stage now...(rusted bolts take a little time)
but i have a weiand 8010-comp 268h k kit-holley 600-exhaust port work-and headers...nothing radical...i shouldn't be running it over 4000...its in a bronco
danlee...i checked out a stock damper at auto zone yesterday and the price was more than i could get a fluid damper for...i'm not trying to cheap out at this point...i'm just trying to put things together without having any problems...thanks for your time in research...do you think a fluid filled one would be worth my time or just go with a new stock one painted??

Summit Racing has the non-SFI approved fluid damper for $239.95.
Non-SFI approved only means it is not approved for racing, but it is OK for a street motor.
FLU-620200 $239.95
Your horsepower peaks at about 4500 RPM, or higher with decent porting. So you might want to figure 5000 RPM. If the price of a new stock damper is close, I would go with the Fluid Damper. I have one of these and my HP peaks above 6000 RPM, but I seldom run that high. I can if I want.

do what???? 4500 rpm???my ears pointed up like a pure bread german shepard (-:
i must be driving like an old man (driving miss daisy??) at 3000...
don't mean to get off topic but i did plan on a gear change 4:56s from 3:50s
at 3000 i'm at 70mph in 4th with bfg 35"
i think i will go with originial balancer painted and save up for a fluid filled...it's easy enough to change when the time comes...thanks

you shuld be able to come up with a hd damper for around $140. I can't remember where I got mine but I think it was a company that had stuff on ebay. As far as the fluid damper, what can I say? I guess there are different stories out there. I think the theory behind them is great.
