so the hd timing set i ordered isnt a ls2 chian? when you say dampaner you talking about the timing chain tensioner that's in aluminum blocks? im running a iron 5.3 truck block that isnt drilled and tapped for it.

 

you would have to drill/tap for the damper

 

i think thats gonna be a last resort how easy of a job is it? i already have the motor apart.

 

the hardest part of getting the damper in would be getting in center in the timing chain so that it dosnt rub either side.

 

if you have the block out and apart and dont feel 100% confident you will get it 100% correct the first time take it to a reputable machine shop and have them drill and tap it for you. They shouldn't charge more than 40 bucks or so to do that

dampener is good insurance against snapping your chain if you beat the tar out of your motor

 

yes the timing chain tensioner/dampener

 

what is the HD chain?

 

For about 10-15 bucks more u can get an OE. I wouldn't do aftermarket, especially when building an engine. Chain is the link that holds all together.

 

i think the one of the left is the hd chain

 

im just worried bout the slack in the timing chain im waiting on a nother timing set from advanced to get in. if it dosnt have as much slack as what the hd timing chain does ill run it. dont wanna have to worry bout my timing chain breaking

 

i built my motor about a year ago and have been spraying 150 on it with about that much slack in it and have had no problems out of it. i have also replaced chains and gears on other 5.3 trucks and had no problems and they have all seemed to have about the same slack as yours

 

i had less slack on my stock chain when i pulled it at 130k miles.

 

That's not a billet cam sprocket in the video. That's a stock Cloyes LS2 timing set.

I've built several LS based engines and they never had this much slack either.

 

Thats what i said it doesnt look billet to me or The hd chain doesnt look any better then my stock oe ls2 chain.ill be pm The seller here soon.

 

Don't want to sound like an advertisement, but I was in the same boat.

I'm doing a build right now and went back and forth trying to figure out what to do about the slack in my Yank set with an LS2 chain. It was about the same as what you show but only had ~2500 miles on it. I went with a Cloyes Hex-a-just because they use a slightly larger crank sprocket to take out some of the slack. You also get a thrust bearing and the infinite adjustment is nice too. High quality piece, and there is almost no slack in the chain whatsoever.

 

I just got done installing a new cam motion cam today, and I also went with the Cloyes Billet true roller Speed set, and I now have very little slack in my timing chain now. I could not believe how lose my old set was.

 

i bought a new set from advanced and the chains look the same. gears look different though.

 

what the add says...

New GM LS complete timing sets
set contains :
Gm crank gear, Gm 3 bolt cam gear for use on LS1, LS2, or LS6 and The LSA/LS9 super HD chain and special Bolts
This is the LS2 HD set that will fit and work great on the LS1 or LS6 engines as well as the 4.8,5.3, 6.0 truck engines

for some reason i thought it said it came with a billet cam gear.... guess i was wrong.

 

I posted a thread post, but it was for LT1 sorry. It talked about an oversized crank sprocket.

 

If you're talking about the set you get from Yank, they have it, you just have to ask. I don't even think the option is more than 10 bucks extra.
