FYI - I just did this job tonite on my 95 LT1. With the correct puller you do not have to unbolt and lift the engine. You do need to disconnect the PS line that is in the way and lift it up.
Also, it helps to have a little KROIL on hand.
One other thing - be aware that many underdrive and aluminum pulleys out there do not incorporate the elastomer ring - thus they eliminate the damping function and that is bad.

You should look before you just 
something because your post is flawed,and incorrect 86PACER is correct
$76 or $40-60 on fleabay ,so you go ahead and pay the LT1 tax if you wish.
Not even close to being the right one.
Yes it is unfortunately how much it costs $600. You can send it off to the damper Dr. to get refurbed There is a place I found for an after market one that I put on my last vette diagnosing a vibration less than a year later it was toast and it cost $300. Consider it a LT1 tax.

There are after market ones but they require removing the hub to install.

obviously not the right one
Hope it works and would like for the OP to post that it is indeed the correct one.
Here it is cheaper

Anothe FYI on this topic is even though the LT1s were supposed to be internally balanced some of the balancers were "adjusted" by drilling them at the factory look on the back of the balancer. Wether this was done to balance the balancer or not it was verified that some were drilled to balance the engine.

If it has a rubber ring between the center and outer ring it MAY be a damper although I have never seen one with that type of center.Do you have a link from where it came from?

Listen since you're a newb and have not been here long enough to remember the page after page diatribes on this issue I will forgive your ignorance. If you care to provide some info on who says it isn't I will be more than happy to read it. All of the info is in the archives. That is why the HB is "zero balanced". That is also why when flywheels are changed close attention is needed to match the weights on the flexplates. Internally balance is a little misleading as there are actually a few weights on the flexplate.It is actually "neutral balanced"

I have been on this earth long enough to forget more than you ever knew. I have been wrenching SBCs for forty years. Twenty of that on Corvettes.
I mean no disrespect to the Forum but it is not the repository of all knowledge. The web is full of balancing instructions on LTXs. With the advent of the one piece RMS in 86, the crankshafts have required external balancing partly due to the reduced size of the rear journal.
Try defending your bogus posts instead of attacking me. You made the statement now answer the question.
The LTX is neutrally balanced on the front and externally balanced in the rear. It is not internally balanced. If it was, the flywheel/flexplate would be neutrally balanced.
Internally balanced is not only misleading, it is false. Spanked twice in one day. You should have quit while you were behnd.

As far as the HB goes we shall see You could get a "F or B' body one for less but the "Y" body one is thinner can you tell me why or why a "F or B" body LT1 balancer won't work? 2 yrs ago they were unavailable after market period and I am glad if they are now because there were few options to replace them.Oh and I guess I should correct myself again they are not a HB but really a damper instead.

All Gen I and Gen II SBCs use a neutrally balanced damper, with the exception of the 3.75" stroke, 400 CID engine. Similarly, all SBCs used neutrally balance flywheels or flexplates (other than the 400) until 1986 when Chevy went to the one piece rear main seal. The new seal necessitated a revised flywheel/flexplate flange that wouldn't accommodate enough external weight to use a neutrally balanced flywheel or flexplate. It is really just that simple.

In the case of the LTX, it is done via the flywheel/flexplate. That is called external balancing. Anything else just muddies the waters.
Spin that. I will be happy to compare AARP cards with you.
I have been polite but direct with you. What age is that acting like?

The rotating mass of an engine must be balanced. Not neutrally balanced as you state, as that is a bit redundant.

I have an idea since you seem to think the forum is not a repository of information and you know so much more than we mere mortals why not start your own forum?

On the LT1/LT4 stock damper/hub assembly, you shouldn't need a puller for the damper, just to pull the hub.
There should be three bolts holding the damper to the hub, on my '92 you just take these bolts out and remove the damper by hand -- although, I have heard of some where the damper was rusted on the hub.
I should point out, my stock '92 LT1 damper came off without raising the engine. After I put on an LT4 damper, I have to raise the engine to get it out -- the LT4 damper is slightly thicker.
