Honestly don't know so I thought I would post my findings here.

Took my front cover off to weld a bung in for a turbo drain and was checking out the t chain and it seems a little loose. Not sure if this is normal or not I have only dealt with gm 4.6 northstar tchains and they have tensioners to keep them tight.

Here's the video lmk what you guys think whether this chain is toast or if that is normal slack.

I don't know if it's just my IPad, but it keeps saying video private, and won't allow me to view it. With that said, LSX engine timing chain have a lot of slack. I was in the same boat when I did my LS2 timing chain on my LS1.

**** yeah it was set to private for whatever reason...fixed public now

Look into the trickflow timing chain damper, it helps with the slack..

Yeah doenst look to be a dampener on there......is there one on the ls1?

If there is supposed to be one then that's not good haha.

Mine is the same way on my 5.3 80000 miles and no problem.

Yeah I showed someone else the video yesterday and he said they are all like that when he has messed with them.

If I really want to get crazy I can stilk just replace it with a new timing chain for an ls2 for about 30 40 bucks. It has been on there for about 50k miles with a .605 238/240 cam and dual patriot springs. Seems to be holding up pretty well imo if that slack is what they call "normal"

everyone ive built has been like that.

if you want to see slack, you should see the belt that drives my fuel pump. they ask for so much slack that i swear it will fall off and my engine will blow up from going lean, but it never does lol.

What many of us do here is to buy an LS2 damper & mod the holes to align w/ an LS1/LS6 block. If your block is not already drilled, just drill & tap on bolt center matching the LS2 damper. Also, definitely upgrade to the LS2 chain while you're in there. There is not a damper made (by GM anyway) for the LS1. That's the reason for the LS2 damper.

An ls1 damper was made just not for long. You can still get one from Katech but the cost about 90 bucks. Honestly though te LS chains have always been loose especially before they had tensioners IMO it'll be fine. An ls2 chain will have similar slack even new

Mine was the same way, brand new JP.

Who needs a tight timing chain robbing HP?

I'm using a Rollmaster double roller timing set in my LS1 and it doesn't have nearly the amount of slack as a stock chain. I know it's normal for the slack in these chains, but I just wasn't comfortable with it, hence the aftermarket chain I am running.

That is already a ls2 chain I do believe. If I remember correctly when I bought the car he said that's what he used.

my stock ls with 80k miles on it had same slack on its timing chain. I didn't like the slack so i replaced it with a nmotion timing chain

Think you're right. All you need now is the damper. Pace Performance part number 12588670, $15.95.
