One place your point definitely warrants study is with the use of aftermarket double roller chains. There is a lot of controversy associated with its alignment. That can be messed up.

I have an 05 and I know mine has it (black plastic buffer). I dont know if there was a production run without it. I havent seen one. Craig's car had it too. I dont recall seeing one not being there. What year car didnt have one? Was there an early 2005 without it?

Anyway, I dont always think failures are all due to botched installs. Cameron's car had quite a few miles on it after the cam install (12-14k?). Sometimes you just get a failure because the part wasnt the best you could have used. Double roller chains exist for cars because single chains arent strong enough. Sometimes its just GM. As I have been slammed before for making a call about some particular part, I try to avoid talking to people who insist on telling me how many chains didnt fail since we know statistics are made from failed data points. Tuner X can say they use LS2 chains and none failed while tuner Z had 4 failures. Its a play on statistics. Tuner X may have done 21 installs and tuner Z may have done 240. Just because someone may not personally know a guy that had a failure, the stat sems to matter more once its your engine.

TJ, thanks for taking the time to post on threads like this. Not many high volume tuners take the time. My installs are too insignificant to produce any real numbers.

 

 

chuck is pulling out all stops aint he? If he has smell-o-vision would he use that too?

 

He's coming, but Ossining Pizza sucks. Cheeseburgers at the diner, please.

 

As far as LS2 engines, all as far as I know had the plastic buffer, as for LS1/LS6 engines and all 2004 and earlier trucks and even some 05 trucks, the buffer was NOT in these engine series. At one time GMPP offered a buffer kit that can be retrofitted into the earlier engines. In most cases it involves drilling and tapping the bolt holes into the block but I no longer see this, however I think the later buffers can be installed.

Sometimes timing chains just break, whether or not they were the OE or the best s**t happens at times. Take for instance a MSD opti spark I had to replace the other day. This was a brand new unit I installed on a customers brand new supercharged 383 LT4 that I installed into his C4. When I was on the dyno it crapped out at 4800 and up. After exhausting all other causes I had to go into the engine bay to replace that POS. Upon curiosity I removed the cap to discover what appears to be a carbon track between two contacts 180 degrees apart. But that really wasn't the problem, I picked the main body up and flipped it over to look at something else, when I did that the damn rotor FELL OUT!!! The retaining screws were never tightened down, and the only thing holding it in place was the indexing pin of the rotor, and the way the main drive shaft had mated into the rotor and the center contact spring force against the center contact!

 

Smell-o-vision...

Thats so precious.

 

I have paperwork to run through today so I cant make it. Ossining pizza isnt even food as I understand the definition.

Why not a good BBQ before I leave? Hot dawgs and potato salad.....some boneless BBQ chicken breast with appricot saucy susan.....pepsi (cafein free). Ah, the simple things that make it seem like all is right with the world.

 

Are either the Cloyes or the IWIS available for the LS3?
I've used the hex-adjust in the past and liked being able to change the advance.

 

Well, took a ride up to Chuck's shop today. Met up with good buddy Craigster05 and met Leon forum member "LSCHLEM" he was getting a 4.10 set up from chuck. Great guy and one happy dude after his gear swap . Hey Leon give'm hell .

Anyway, did a lot of shop talk and checked out my beast all torn apart in the engine department "compliments of chuck and gang ." Chuck took out the worst piston with valve contact "all cleaned up" and showed that there is virtually no damage to the piston and that the rod bearing has average wear and tear and quite clean. Chuck will start another thread on this rebuild. I am not going to divulge much more, but lets just say, I am confident I will keep my Vanity plates "WLCM2TRY" for a long time to come .

PS : IWIS timing chain on the order list.

 

Yes, it was a fun day, how's that Bacon Cheeseburger treating you about now????

 

I needed that after eating organic salads for a month. Stop talking about food might get spin to post opinions about chuck's pizza .

Great day..I am a horsepower junkie..

 

Don't learn the hard way, if that cylinder had contact replace the piston, connecting rod and obviously the bearings. It's not real good when it goes back together and there is a problem, I'm not saying there is going to be but it's apart now, what would it cost to replace a connecting rod and piston vs what would it cost to tear it all apart again and still replace them. Just my 2 cents from experience.

Ed

 

Appreciate your opinion, however, from all aspects of scrutiny, there were no adverse effects in integrity versus performance of these pistons coming from a reputable tuner with expertise. BTW, I saw the pistons for myself. I made the decision to stay with these pistons not the tuner, he just gave his opinion. Appreciate your input and thank you...

 

Cameron when I seen your engine all apart it seemed kind of sad. We talked to Chuck at considerable length and he has all the confidenances
that you will be back and running soon. You were very lucky even though many valves were bent. Chuck will find the right timing chain
that will hold up. Thanks for the compliments on the diff and i will have
much to say about the total experience there in ossining. Leon

 

Hi Leon hope you are having a blast with those 4.10's. Thanks, I am confident Chuck will make things right again.

 

Stroker...Stroker....Stroker.....Stroker ...

 

Hey Cameron! Sorry for the sidebar, but what's the story with that 442? My Vette shares the garage with my first love, my 71 442 vert. One thing's for sure, my 455 in my 442 can't hold a candle to my Vette like that one did.

Nor could my built 455 in my 72 Hurst/Olds:

 

Hey Joe I thought the 442s had posi??
Mike

 

He has 500rwhp with that 442, he claimed low 11's on the 1/4. On the roll I beat him by 2 lenghts 2nd into top of 3rd. His 442 is for sale very clean...
