I dont know much about the L1 engine, but I did drive once a 64 vet and a 66 vet,,,can I have one now..lol what a great car
Full Throttle Testing of LS1 Corvette Engine

It isn't that much, since no cold starts were necessary. If the temperature of the metal in the engine(bearings, piston rings, cylinders etc) is constant, much less scuffing will occur and less particles will contaminate the oil.
But, I guess they could have stopped it a few times, to check the oil level(or changing oil filter)?

IF the engine was run exactly at redline under "full throttle". Trying to keep this a real as possible, if you did that with the engine in a coupe that would be equivalent (in 5th gear) of 175mph. Doing that for 520 hours would equate to 91,000 miles, under maximum load and rpm.
I'm sure a lot of other engines could do this too, but it is still pretty amazing to think about. Almost 4 times around the Earth at redline!

I'm sure oil degradation is completely taken out of the equation. Since they can transfuse blood without stopping a heart it's reasonable that GM can transfuse motor oil without stopping an engine.

I tend to agree.
The test was of the engines not the oil. It would not make any sense to run the oil longer than changes dictated by the GM's oil change monitor.

true story.
years ago,i worked with a guy that had just bought a brand new trans-am.i forget what year it was,i think 98 or there about,but i do remember it had a corvette engine as he kept talking about it.i think it was the LS1,or what ever.
anyway,this guy was extremely happy with it ,as he should be,since it was a heck of a nice ride.i remember one morning his brother coming to our work place and asking if he could borrow the car.at first,he refused,arguing with him on how abusive he was with cars,but he finaly gave in and lent him his baby.
long story short,his brother finally came in the after-noon to return the car.the first thing my freind did was to pop open the hood and take out the dip stick to check the oil.i didn't know why at first and found it kind of odd for him to so quickly do this.
he looked at the oil on the dip stick,turned around to me and said,...you see,this is why i don't lend my brother any of my cars.
the oil had some kind of fine metal shavings that were clearly visible that he knew was not there before. he was REALLY ticked off and nearly got in a fist fight with him right there.there was also a burned smell coming from the brakes.you know,that typical burnt brakes smell you get when you give them a real work out.
again,i forget the exact year and what the exact model name was,but it's a true story.
i also remember racing him with a 944 turbo i had back then and dusting him,but that's another story.
i'm not trying to say one way or another anything bad about GM engines,honestly,..it's just a true and funny story.
i guess the moral is,in the wrong hands,any engine is in peril.
...and i don't know what oil was in there.

I wish I could drive my LS1 Corvette for 21 straight days at full throttle!

Even if you could in Julian Fantino's Ontario you'll have to stop for gas; I'm guessing, every half hour or so.

Heck, with all the snow we got around Washington D.C., I wish I could JUST drive my LS1 Corvette ! It has been sitting in the garage with the battery tender on it for over a week ! It's 4 wheeling time now (Nissan Murano) !

I hate to brag, (well not really) but we've had virtually no snow up here in the Toronto area so far this season.

You've jinxed us now!
Seriously though, I said at the beginning of this season that I bet this winter would be virtually snow free and I still believe it will happen. We've had less than 12 inches of snow for the entire season so far, and no major snowstorms in sight in the next two weeks too.

In the "olden days" many motors had a limited life at full throttle, without knock sensors or enough full throttle enrichment - catastrophic failure often was at hand after only a few minutes. From actual published engineering tests ( only slightly clouded by memory)
Middle 60's: Ford exported some Mustangs to Germany, many blew up within the first few weeks. No one had anticipated that the Krauts would take em out on the autobahn and hold the throttle floored for many minutes at a time. Huge improvements in cooling, enrichments, reduction in timing advance were required to fix the problem.
Middle 70's VW announced the new "Rabbit Motors" were tested to run at 600 hours at full throttle, at either the HP peak or the torque peak. Tech articles indicated that this lengthy testing at full power had been rarely performed on passenger car engines before that time.
Later 70's Internal documents showed that GM's ill fated "Oldsmobile diesel" never achieved more that a couple of hours of full throttle operation despite an internal goal of at least 50 hours. Blocks shattered, crankshafts broke, gaskets let loose, despite all these fatigue related failures it was put into production anyway.
This cost the Oldsmobile division many of their loyal owners, these engines suffered the same failures as the miles piled up.
Now, the Chevrolet engines can run for 100's of hours at at full throttle.... producing huge horsepower... impressive indeed!!!
Yes, I know that older tractor engines and their ilk also could do it but they were often producing only 50 to 60 horsepower out of 200+ cubic inches.
Now it is certain that the Corvette motor would last much longer at full throttle than your drivers license would!!

It took me about an hour to compose the last post, as I was distracted by opening Olympic ceremonies. In the meantime, this thread switched to a snow report.......
In Cedar Rapids it seems like it has never stopped snowing this winter. Pulling out at intersections is suicidal, no way can you see if anybody is coming over the snow piles.
But the skiing is great!!!!..... but we have to ski off the haystacks and manure piles to get vertical.
OK, Canadians, I have skied Whistler-Blackcomb, it is superb!

I have a client in Ames, and I was there on Thursday. Once I left I went to Theisens (Hwy 30 and Dayton Ave.) to pick up a few dog treats. It was a challenge pulling out on Dayton because of the snow piles. I had the Caliber and had to carefully ease out onto Dayton because the snow piles were higher than the car.

We're going cross country skiing on the Chichaqua trail on Saturday. We'd like go from the trailhead in Bondurant to Valeria and back-about 24 miles.
