I have read about some other valve guide material, was it inconel? Cant remember off the top of my head but it was something high tech sounding, lol.
There is a shop in LA where my buddies dad works, they make very high end valve guides for racing, etc. He is also a Vette owner and I am supposed to call him to get the rundown on what they are using for the LS7. I will post what I find out from him.
Even on hot days I never see oil temps over about 235 on the track and I run the **** out of it there.

- on the old school small block and big block carbed motors. However most of them were only pushing at most 300 rwhp and that was a very hot factory muscle car.
. If you were getting an old school carbed motor up in the 450 to 600 rwhp range they were pretty radical , letting loose & punching rods through the side of the block quite frequently- let alone they were hardly streetable and you could not take them on long road trips like the OP did with his 581 rwhp Z.
It would be interesting to compare the failure rates of a carbed LS motors compared to electronically controlled fuel injected ls motors. I doubt if there is enough of a representation of carbed LS motors out there.
The OP has a good attitude about it. If my LS7 blew I would probably go with the 454 LSx motor upgraded heads and forged internals. I would shoot for 550 rwhp. I would not care about the extra weight up front.

Inconel, it's a registered trademark name. It's an austenitic nickel-chromium based alloy. Usually they are used for valves (exh valve) in very high combustion chamber temps such as turbocharged engine. If I recall correctly, most piston engines for airplanes uses an inconel valve. I know it is used for turbine blades as well.

maybe a later ride
The 2010/2011/2012 Z06 have the ZR1 oil cooler which uses coolent from the engine to keep the oil cool (they did it because the oil temps on C6 Z's never get warm) and they run at coolent tempature once warm even on the track according to those that own them. I have pestered my contacts at GM to see if this is as easy to do to a pre-2010 car as it looks and they look at me like I'm an idiot for not just buying a new one.
Also, my 2004 runs at 250 on the track with an aftermarket cooler, but if I just go out for 5-10 laps at a time at 9/10's, it will stay at under 240 all day.

Let's not get carried away here and make things out to be worst than they really are, as the original poster in this thread engine blew at least 3 months ago.

I have no idea but my car just does not run hot even when driving the **** out of it on the track. I always run the DIC with the oil temps showing. My car is an 07, no cooling mods.
My buddy in town I race with has a 06 Z, he probably does not run as hard as I do, only been running the trak for a few years, has the same temps as I do, we just thought this was normal.

I checked his sig, but he didn't list the year of his ride (I don't either, I run a 2004 looking to upgrade soon).

It doesnt really matter what year you get, its happening to all of them.
My car has a pretty big cam in it with long tube headers. It had a valve spring upgrade and Ti retainers when they did the cam. Also long tube headers and high flow cats. Its runs very strong.
I was heading to the drag strip to run the car and when I got on the freeway it started missing. Turned around and came back home, pulled the valve covers and found a broken spring. Was not a big problem since I have double spring and only one broke.

You bought it used. Maybe it has larger radiator and oil coolers. Believe me nobody runs 235* oil at the track even on a cold day. What is your coolant temp?

I just could not afford a new one at the time so I got a used 07 with 24k miles and some mods for $40k. Then third gear went out on my tranny so I installed a newer T6060 trans in it myself. The new tranny cost me $2900 shipped. The seller actually paid for a good chunk on the new tranny too.

DH, I agree. I don't know what the drag race guys are seeing but I have never been under 275 oil temp after lap 2. I never rev the car over 3K until the oils at 125-139, which doesn't take long, and I don't leave until the oils at 90 100 degrees.
I originaly thought that 275 290 were really high temps for a car that was designed to be on track as part of the base design but after my first 2 track days and asking people I found out this was the norm. I added the Setrab oil cooler, It is about 15" x 12". (the big one) with the Canton oil filter to increase flow and get some margin for VIR, Road Atlanta and the Florida track, Palm Bch, Homestead and Sebring. I was seeing 290 295 and had to really get more conservative in order to stay at those temps on the hot August days.

Are you guys working on your cars yourself? Some of you guys need to spend more time at the track and under the car instead of the forums. Some cars run cooler, others hotter, etc...Dont know why thats so hard to believe
Is there still a camp of believers out there that think nothing is wrong with the LS7? Sounds like GM is finally trying to figure it out, cant wait to hear the outcome, for now people are getting engines replaced alot easier. Wonder if they are going to come out with a fix before the grenade.

Have you ever heard of GM (or any large corp) admitting to anything in public?
For instance~
The DOD still denies agent orange is harmful, as the men that got "dusted" kick off like flies because of respiratory issues....

I was a mechanic for 20 years, have been inside and out of my car, the cooling system is stock.Did the tranny install myself, built my last two C6 cars and my C5.Had the fastest bolt on car with my black C6 at the GM VS Ford shootout few years back. Mel's blue 06 is mostly stock except air filter and tune. When I did the air filter install a couple months back I was all around the Rad and front of the car, all stock.

I don't drag race I do road race, and I think that's the difference here. We are doing 10-20 laps all out so I think the heat would be different. I have a modified from radiator and now have a much larger cooler than the stock front cooler. Most stock oil cooler cars and drivers I have met over the last 5 years have all been around the 270 290 mark when they're on heavy laps running all out.

I believe your car has stock cooling if you have checked it out. Just figured it was a possibility since you bought it used.
You know I have lots of track time and have talked to many Z06 drivers. You are the only one running that cool. Even the guys with bigger coolers are not running that cool.
So I figure the only other explanation is that you are a BIG FAT SLOW TURD on the track and run around in 5th gear. If you don't think so then show up at ACS on saturday

I assumed Matt was talking about road racing. I have been on the track with him before.
Sorry if I asked this already. Do you have oil temps for your new cooler setup. Bet you would be very suprised if you could get 235*
