LS2 Timing Chain Dampener on LS1 Block?

The link below says you can use the LS2 dampener on a LS1 provided your LS1 block is NOT already drilled for the LS1 dampener. I imagine you just drill the LS1 block to accomodate the narrower bolt centers of the LS2 dampener. Only question would be were exatly to drill......

Your thoughts would be appreciaed.

BTW, my block is NOT drilled/tapped.

I drilled/tapped the block & installed the GMP damper on my 2001 ZO6. The raised bosses on the block are spaced too far apart to use the LS2 damper.

Well that just sucks..... I thought I had a solution for installing a dampener.

Rick,

Did the drawing help? I think a piece of bulk nylon could be used to do this with some metal inserts.

Is this really needed if you use a high quality timing chain set like the Cloyes Hex adjust 3153AL?

Depends. Normal street driving probably no. What is does is prevent chain whip at certain RPM where there are known issues. If you run on the track then it may be a good thing to have (track being HPDE rather than drag racing where you pass through the RPM range quickly). This is at least my understanding of the issue.

Another thing to be careful of is to make sure the two sprockets are aligned during installation. This should be checked with the chain off, then install the chain.

Making one from the drawing is at the top of my list. If I could just use the $15 LS2 dampener that would be a no brainer.

Might even be easier to buy a black LS2 dampener as a "mold" and drill it to the ~2.1" LS1 bolt centers.
