I did the LS6's one time and I beat the hell out of my cam bearings and stretched a factory 05 timing chain in no time, plus I spent $160 on Toyota land cruiser seats, rather than retrofit LS6 ones, and I had to use press on 2.2L cavi seals, which I've been told can fall off and get wedged under the springs... I didn't have that issue though.

I sold the springs and seats once I got rid of the milzy cam and went with the 986's because of my 568 lift... the other 918's and 915's or whatever they were wouldn't go that high, and were too stiff, and once again needed custom seats, and seals.

Barry, you sure it wasn't Turbo+Cam ?

I'm kind of thinking about some of these 986 springs myself. I don't plan on revving over 6k, but boost isn't out of the question.

It'd probably be a good time to order an older style set of gears and timing chain too at that time. I doubt the Cloyes set would appreciate the stiffer springs.

Nope, buy a factory GM set and send them for cryo treatment. I did that this year. The cloyes sets seem to have the gears made from a cheaper material.

I really want to pull my headers and send them to get Jet-Hot'd this winter too. Doing that and then doing the timing chain and valve springs would be a nice upgrade all at the same time. I'll be damn tempted to just pull the engine and then toss a cam in it too, but I really like the idea of having an internally stock engine for reliability's sake.

Is GM the place to go to for the older timing set? Or do you by chance have part numbers for it? Or another place where a guy could get both gears and a chain?

I don't know if this should be pinned somewhere, but here are the P/N's of all the timing components for a 94-99 3x00 motor.

Crank Sprocket 14074400
Chain 10166352
Dampener 10166353

I'm also sending mine to www.nitrofreeze.com on Wednesday. A whopping $37 will treat the whole timing set, turn around time is "in by Friday out by Tuesday" They do batch jobs over the weekend only for their racing department(to keep it cheap) so turn around can be 1 week to 1 weekend... depending on when you deliver it.

I went direct to a GM dealership to get the parts, I know you can get them on Parts Direct if you don't mind the wait they sometime have with shipping.

all of the times ive ordered from gmpartsdirect i got my stuff either within the same week or early to mid part of a 2nd week depending on the day i ordered.

I only say that because it once took them 1 month to get me two transmission gears.... which ended up being 93 3t40 parts when I selected my 95 for the car... I was pissed.

the only time i had a problem was way back when i first got the grand am, i bought a headlight retainer ring and it got lost in shipping and i had to fight to get a refund.

i usually anticipate extra time when i buy stuff. you know that when your waiting for a part/item to finish something up (like my lifters that one summer) and it takes longer to arrive you get kinda mad.

Cool, the set prices out at just over $100 through GMPD before shipping charges. There is also a pretty good sized Cryo place in Iowa that I'll contact for a quote over the coming weeks here.

I really feel like getting a spare set of 3400 rods to send too... then polishing them when I get em back.

my timing set from gmpartsdirect was around 140ish shipped.
i think Jon paid about the same.

Im not going to play with the chain. The one on my current 3500 is mint. I dont think just valve springs will stretch it, its a roller cam, theres so little friction. Its more of the snapping back and fourth motion as the chain gets loaded in each direction that could stretch it.
Oh well.

It will stretch over time, roller cam or not. I've stretched BOTH versions factory 04+ ones, and Cloyes replacement 99 older ones. Not sure how the OEM frozen one is holding up yet

I am curious to know after 10K miles. You put any serious miles on it since the new chain assembly?

No not really... The only places its been since the new chain was Albany NE fest... and just around town and such... I don't think its been over 2k yet.
