Who makes the strongest timing chain?

[torq455]

unless the chain is prestreched, all timing chains will stretch. the question is how much more will it stretch? measure it now, then check it again when you tear it down again. that will tell ya if it's wearing fast or normal wear.

I went with the older style on mine, I had a spare from a '99 so I went with that. The newer thin style though, according to GM was made from a stronger material. I have quite a lot of mileage on the engine and since my last teardown just to do a visual inspection it was just fine. However hey i'm my '89 Z its very easy to re&re

Is that doccumented anywhere?

my '04 chain stretched after 800 miles...

Actually taking out the spark plugs and turning the engine over with a ratchet you can tell if it has slack by listening closely. If it snaps when you first start turning then you know.

JMo60, taking off the cover lets you know exactly After replacing mine the engine now is very, very, very, quiet running. No ticking noise anymore. (was slapping the guide)

The blanks are at the gear cutters now. He said it would be a couple of weeks then they go to heat treat and to EDM.

No special cover or electric water pump. The DR set will fit under the stock cover with little or no grinding. The oil galley plugs have to be shortened so they don't stick out of the block. Most everything else should clear.

EXCELLENT!!!!

Ooh, any rough estimates on pricing for the double roller sets yet? As much as i hate spending money LOL, that's would be a FOR SURE thing on my list, even with the mildest cam, and my cam isn't mild.....

[blackbombshell95]

I'm ready to buy a timing set now. Get those to wot-tech asap!
Also, any plans for an electric water pump for the 3400s?

[JMo60]

How do you guys know when your timing chain goes out or stretches too far.. I have been using my same one forever and havent noticed any problems

Patience grasshopper... double roller TC sets are in the works.

Just out of shear curiosity, is there an update on this?

[Rhedalert]

I wouldn't think so (regarding electric pump)

The GM service manual shows you can have a max of 1/4" play at a certain point. If noone has the exact spec, I'll look for it and get a scan.

Is there a certain amount of slack when a new timing chain breaks in? Mine has 500 miles on it and i want to make sure its not defective before i put the cover back on. any input appreciated.

[blackbombshell95]

For FWD doulble roller applications we will need an electric water pump? I suppose you will offer one of these too CNCguy?

[34blazer]

the Pete Jackson ones come in 2 flavors.. Noisey and quiet. I'll see if i can find a video of mine, i had the noisey set.

noisy or quiet, they still can register knock.
