"The crank has been turned down to LS bearing specifications (to reduce surface area) and LS bearings are riding piggy-back on stock bearing shells"
I think I understand what's going on with this engine build except for the bearings.
This sounds to me like an LS bearing mounted inside the OEM shell.
Is this correct?
How do you keep it in place?
Wouldn't this be more prone to spinning a bearing?
Maybe I'm missing something?
They don't spend a long time discussing this detail. But the builder states that "by getting the crush just right" there is no chance of a spinning a bearing. This suggests to me that 'tangs' in LS bearing are biting into the stock bearing shell material when the crank is torqued down. I am not sure if LS bearings are staked - but if the stake lined up one the stock bearing shells that would be another way to prevent the LS shell from moving.
