When you spin a bearing, what happens to your engine?
I've heard some stories of people spinning bearings, and I certinaly wouldn't want that to happen, but what do you usually need to replace when you spin a bearing?
Is the block all shot up? Oil pan have large holes? Top end destroyed?
Also if the timing chain snaps, does the engine kill itself, or is it protected somehow? (And do timing chains really ever snap?)

a spun bearing usually hurts the bearing,i have seen a few that hurt the rod as well causing replacement or resizing of the rod,if a main goes it can do damage to the block in which case you will then need to have the crank mounting surface ALIGN BORED this brings it back to its normal geometry,in the 18yrs. of hot rodding i have,this has happened 2 times and a 3rd being 2months ago in my z28 @112,000 heavily raced prior to me and blown headgaskets no worries a new engine will be in this week..still sux!

What causes the stock GM timing chain failure? I just changed my cam recently and replaced the chain and sprockets to be safe. The original looked good at 30k, crank sprocket had minor wear on teeth. I ran up to 6200rpm frequently, 1.6 rockers ,crane dual springs. Did the failures mentioned in this thread happen at high miles or was the application more severe, very high rpm or high spring pressure?

Did you increase the spring tension?
You should have got the LT-4 ED Cloyes chain.
Sometimes the two sprockets don't line up.If viewed from the side one may be out farther then the other or not on all the way causing the chain to run at an angle. Will break a chain in short order.
