Which timing set is recommended for durability/high performance 3400 engine?

1- the older design "pre 99" set which has 64 links, 3/8" pitch

or

2- the 2003 revision version2 which has 80 links, 8mm pitch


Experts chime in please.

Thanks.

GM 94-99 chain. That is the best chain short of the TCE double roller. Not sure between the cheap aftermarket 94-99 chain sets and the 00+ sets.

94-99 chain and gears directly from GM.


a gen1 timing set would be very nice, those things are HUGE but you'd have to space the timing cover way out to use one.

Isn't the cam sproket held on by 3 bolts instead of one large one also ?

Or should I put a Gen I set on my 3500 with RWD timing cover ?

yes it is, but check this out.

GenIII motors use the same crank sprocket as genII motors. the genI and genII sprockets are different, but maybe we would be able to use a genII chain. is that any better than the early style GenIII chain?

you should be able to modify the gen1 upper sprocket to bolt to the gen3 cam.

The important thing to know is the actual strength of the chains, thicker isn't always better. The gen1 and 2 chains could be made with a different grade of steel, hardened to a different spec so that they are actually weaker than the gen3 chains.

We don't actually know if the pre-99 gen3 chain is stronger than the 00+ however in my personal application i had a '04 chain stretch after a few thousand miles of abuse. My 99 chain looks the same as it did 2K miles ago.


The aftermarket chains for the gen3 engines have failed miserably: http://60degreev6.com/forum/showthread.php/43914-Timing-Sets.?highlight=timing+chain


If you want the best performance chain, TCE's double roller is the answer.



Something else i've been meaning to look into is the timing chain tensioner from a 3.4 DOHC: http://i614.photobucket.com/albums/tt221/Smittro1/tdc006.jpg

Looks pretty slick.

Yeah after pricing out the GM parts I decided to get the TCE set. lol
Everything is at the machine shop anyways so whats throwing the crank on the lathe for a few mins. The 3.4dohc tensioner looks hot !! hmm Wonder where i can my hands on some spare parts to fab something up.

The 3.4Ldohc tensioner is only $26 on rockauto. I might just pick one up and play around with it. Just need to figure out how it is hydraulically actuated.

I have a 3.4 TDC timing chain tensioner in the garage.

It came off a used engine and I have not been able to get it set back in a position that would allow me to install it. I'm not sure if there's something damaged on the one I have, or if the spring is just that strong, that once it's released, that's it.

I picked up one from rockauto for cheap, The spring is uber stiff, and the mounting holes line up perfect with the stock 3400 one =) I don't have a block handy, but I'm going to see how much modding it'll take to the cover to get it to fit once i get that far in my build. I got the TCE timing set in the mail and it looks very nice and solid. Looking forward to finally putting this thing together.
