Who here runs a double roller chain with an LS2 dampener? Maybe not necessary, but my main question is going to be if there is any interference or rubbing with running one. If there isn't, for $20 or so, it wouldn't be a bad investment I would think.
Couldn't find any really solid answers to this question from the threads I found on here.
What engine is it on? I know there are a few LS engines (LM7) that don't use any sort of dampener or tensioner at all. There are no bolt holes for one.

L33, which if I remember should have the holes. If they don't/didn't, then I would not even bother haha.
I've retro fit them to iron 6.0 blocks using a transfer punch, 17/64 drill with collar, M8x1.25 tap punch and shop vac after careful placement, it's not difficult, measure twice before tapping your punch. Did not use double roller chains.
I read somewhere on one of these forums that someone makes a thicker damper for use with double roller chains, would make since so the entire section width of the chain(s) can make contact with the damper. Most of the time I don't see a damper used with Double Roller chains, even tho I would prefer to use something.
Can anyone confirm if there is a thicker damper for use with double roller chains?
I have an LM7 right now that has no guide and no holes. I want to run a guide. What do you recommend?
If you want to use the LS2 style damper on a block that has no mounting holes, simply use this adapter:

It's not needed with a double chain but necessary with a single. The single whips around and can break. The double has no slack in it.
The dampers have the ability to dampen harmonics. Both loose and tight chains regardless of being single row or double row will still have harmonics. A tighter chain will behave differently, but it still has harmonics. I run them any time that it is possible.
