Oil pump is tight from the bearings pieces going through it. There is really no way to know what happened unless you measured everything and checked everything properly. The fact is If everything was properly done it wouldn't have failed. I'd have crank checked and the line bore on the block checked.

I haven't talked to the engine builder yet, ill be going over tomorrow. To see what he has to say. Regardless I will need it fixed. Question is how he will go about it. I havent checked any of the clearences And I could measure everything. But just don't have the time, and am missing a few tools to do it. Once I have my shop organized I will start building my own engines. Yes it's a iron 370, forged rods and pistons, stock crank.
Funny thing is I've built mud pumps for drilling rigs for about 7yrs which is abouth the same thing as a engine. You have 2 main bearings that you use crush gauge, toque it down to spec, untorque check crush gauge, but instead of boring you use shims, has 3 rods, 3 cross heads (pistons) that also have to be shimmed. So

yes I did, the Comp Cam was never heat treated correctly and despite having new oil pump and the cam being new it locked up on my bearings twice. after the first one I had a machine shop check the journal sizing and straightness and it checked fine. without lifters etc it spun free as could be when in the block cold

The oil pump is probaby tight because the outer gear has rubbed up against the pump housing or cover. Usually the bearing material is pretty soft, I doubt if he has chunks of bearing material in the pump. The oil filter and pick up screen would have caught that.
It does not take long for **** to go south real quick so maybe you had an intermittent oil supply issue. The LS oiling system is one of GM's downfalls when they designed these blocks.
