The timing chain damper for the ls2 doesn't fit the ls1. The ls2 version has the bolt holes spaced farther apart.
GM hasn't sold the ls1 version for a while now, so as far as I know there are now timing chain dampers available that work with the ls1.

Um; yes it does. 04+ blocks have the proper spacing & as mentioned...earlier blocks need to be tapped. The pic I have shown is the LS2 dampener installed in my 2000 block. Holes were tapped by me prior to installation. My 06 block has the LS2 dampner as well, as mentioned, proper spaced holes already exist in this block.

Yes & yes. There's also a pic floating around in here where a guy replaced the center section of the LS2 dampener w/ aluminum so that he didn't have to re-tap the spacing on his pre-tapped LS1 block.

Here's the thread where someone modified the ls2 damper to fit their ls1 block: http://forums.corvetteforum.com/c5-t...ls1-block.html
He modified the damper to move the bolt holes farther apart. His block did not have the holes drilled and tapped from the factory. In that thread I specifically asked about drilling the block so the holes line up with the ls2 damper and he thought the holes would be too close to the the edge of the embossed part of the block. In the pic below you can see he marked the centers of the ls2 damper holes on the block and they do seem close to the edge.
Of course, I've never actually seen that part of the engine or an ls2 timing chain damper, I'm just going on what others have posted. If you've successfully done it, that's great to know and I'd love to know more!
Do you have a pic of your ls1 block with damper off to show where the holes are? Also, how did you line it up and determine where to put the holes?
I'd really like to have a timing chain damper, but drilling my block is also kinda scary.

I really don't see the issue. The physical size of the LS2 dampener fits all blocks. One can either make excuses about how to get the holes to work or just figure out how to make 'em work. It's really not a big deal for most guys who work on their own ****.

here is a thread

I have been studing this chain damper and I have an idea that might make it work on an LS1.

Since this thread was first started, there have been some issues with the spring loaded LS3 damper and guys have been going to the LS2 damper instead. Having said that, the LS2 damper is cheap and I would personally buy a couple and figure out how to get the hole spacing to match the LS1 block then drill the block.

I actually just did this to my block using the LS2 dampener on my LS1 block. You do have to drill and tap unless you have a newer block that has already been drill and tapped from the factory for the LS1 dampener. Happened to a friend of mine. It is doable but i did mine with the motor out of the car. We used a vacuum to try to keep metal shaving out and cleaned the drill and tap constantly. Also you will be very close on the sides of the bosses but you should be alright.

Wish i had been more on to it about the damper when i had my engine built, would've saved me a lot of $$$$$ & heartache from a broken Dual chain road racing.
Engines repaired but the workshop wasn't prepared to drill into my block to fit a damper,
