Welcome from Calif,You may want to go to the GM Performance section with this.Some very sharp members could help you out on this

 

i tried that already everbody reads it but they dont respond

 

wow, never heard that.. Are you sure they were all the right size? also was the cam for the motor? Not trying to cut you down or anything, just curious of facts.
I just reused the cam bearing on my 6.0 I just rebuild and Im not real worried about them.

 

Welcome, and sorry to hear about the problem, its not common at all. in fact your the first i have heard with this problem.
Do you know what your injector duty cycle is? they have to be beyond maxed out.

 

Your sig says lean with stock injectors, shouldnt you be running more then 44lbers?

 

cam bearings were for a 02 and older no problem going in i thought im used to conventional motors cam was a xer273hr-14

 

there were at 100% i was going down to get my new tune when it let go i was puttin 44lbs motacs in it

 

44's will help, 80% is when you want to plan for bigger. I wouldnt doubt the failure is from going lean

 

What year is the block?
