Does anybody have a clue why?

That's what we've done to the Wood Hauler's 408, but his 99 6.0l block already had the holes drilled and tapped so he just ordered the dampener and it included the bolts. We also got the LS2 timing chain and sprocket set but the sprockets are the same so just the chain and dampener should stabilize it a lot at the higher rpm's.

you need to pull the cam and inspect it.
it is not like your running a solid lift cam on triple springs.
it is a roller cam with roller lifters, some thing is being held in a bind.
check the heads too, rockers and valves for any thing that wont move.

I have never heard of a chain breaking in anything over the last 15 years i've been hot rodding. Something is seriously wrong.

I know guys, all of these thoughts could be......but the weird thing is that the first time happened with the stock cam (motor was never touched)
. Now it did it with the aftermarket cam. It lasted exactly a year since I fixed it before. I fixed it last year in March 2005, upgrading it with the cam.

Sounds like no matter what kind of chain you install it will keep breaking until you figure out why,I was thinking like the other guy mentioned a bad main thrust bearing,what can cause that is the torque converter balloning and pushing the crank forward,balloning converters are sometimes do to a restricted trans cooler in the radiator.Check your crank end play.
