Crank and rod clearance numbers???need info
 

Hey guys just picked up this high mileage 5.3 for a rebuild motor wasn't knocking but want to tear down and inspect.I want to plasti gauge the mains and rods but never done it before so looking for the clearance specs.im usually pretty good at googling something like this but can't find what I'm looking for

I think factory is near .0015 for mains and rods arent much further off. Is this an iron or alum block?

Not 100% on those numbers.

Here you go.....
