Yep i'm in the club, at least I think so heh. I had a nice knock going for a while which led me to installing a new motor, though I never did take the old one apart. I think at this point i'm too scared to find out it was something silly and I had my car down for over a year for nothing lol! Oh well, here's to new motors..

I didn't spin one bearing, I spun 4. I took some time away from the car, thought about selling it, but it looks like I'll be rebuilding it and beating on it again shortly.

I actually plan on putting some useful information in this thread. Maybe it'll become a sticky?
Low Oil Pressure? Look into a new Oil Pump
You can bypass chaos caused by overspun bearings buy purchasing a heavy duty oil pump. Prices range from about 100-150 and to me, it's considered cheap insurance to keep your LS1 happy.
Texas-Speed.com: Ported and Shimmed LS6 Oil Pump - 139.99
Thunderracing.com: Ported and Shimmed LS6 Oil Pump - 149.99
SLP Heavy Duty Oil Pump: 185.99
Stock LS6 Oil Pump: 99.99
Melling HO Oil Pump: 139.99
Porting the Oil Pump on your own:
The path where oil pumps out from the oil pump is very disruptive and has many ridges. Take a grinder and port the hole. Like porting heads, grind out any surface irregularites to ensure a smooth oil flow. Next would be the installation of the spring. You could shim it yourself or purchase a shimmed spring which, in return, will have better pressure relief than the stock spring. Clean the pump housing and tighten the plug to 12 lbs. Be careful not to tighten it too much! When inserting the outer and inner gear, use a coat of grease for protection prior to startup. Place cover on and tighten to 12 lbs. again.
Stronger Bearings?
You could also purchase a set of stronger, heavy-duty bearings for a relatively cheap price too. They are priced at just under a 100 bucks. You could go with Federal Mogul or Clevite Bearings. Changing bearings? While you are in there, might as well go with stronger Connecting Rod Bolts from ARP.
So about 300 bucks, could save you from about 4 to 5 thousand or more dollars in a new assembled engine.
Tips: Check your oil religiously.
LS1's seem to suffer from oil starvation quite a bit. We all know to change your oil 3,000 miles and to regularly check oil levels. Be concerned also, when you have lower oil pressure. This could also be due to a different thickness levels in the vast array of oils out there. Thinner oil will read lower than thicker oil and hotter oil will read at a lower oil pressure than cold oil. Most of this is pretty much known information, but just in case you don't know, now you do.

Slamming it into 2nd gear at the top of 3rd (105mph) slams valves into pistons, causing them to bend.
Bent valves make your car run very rough.
Continuing to drive it this way for a month and a half (and not nicely at that) eventually spins a main bearing, especially after racing a friend.
A spun main bearing drops your oil pressure guage needle to 10psi and you hear a faint--solid--knocking sound from the bottom end when leaning under the car.
Pulling this dead stock motor means you're going to spend a ton because you can't go through the hassle of swapping a new motor in without doing heads/cam/intake/pully/headers, etc. Also had new cam bearings and installed Clevite CH-series rod bearings with ARP bolts. It was a low-mileage stock bottom end.
I also spun 3 rod bearings in my old 305 third gen when the trans hesitated on a 6000rpm shift on stock bottom end
..........it then got a forged 355

Wow, I am learning alot! I remember during the summer, I went 1-2-3 back to 2. It wasn't a high rev, fast clutch action but I was afriad I might have bent a pushrod. It ran strong as a **** though afterwards. I wonder if that had anything to do with it.
Looks like a lot of folks with overspun bearings have great success stories, despite our services!
