Very true.

Rod bearings .002 +-.0002
I mod about ten locations on the block.
I am changing my turbo setup now and have no aem logs saved I can show oil pressure on. Very soon though I could post logs.
I in no way am saying this is the way to do it but for every engine I have built for customer/friend I may or may not change the oil pump size depending on clearances and what the engine will do.
I can without a doubt say that all of the motors see 8k or more daily. All run the block mods I do as well as ported/polished pumps. I do not usually shim the relief however.
