Well if you’re getting bearings on an engine that has been unopened then obviously standard because it wouldn’t have been machined.

I have a bearing 0.50 on it does it means the crank was cut to 20 thousand?

clearances affect oil weight more than the bearing material driven oil has a chart guide for rod and main clearances for both aluminum and steel

Did you ever find the answer to this question?

What bearing would I use for late model performance? The Tri metal bearing is always brought up when some one says performance build always followed by 60's/70's muscle car...what about 2008ish muscle car?

De 1st one has for giving material, for people who should change their oil more often, especially if short drives to daycare. Maintaining the PCV system will help as we as an oil catch can, but use use name brand correct valve as this is a calculated vacuum leak except at idle when it closes due to vertical weight or spring. Some are drilled with no valve. The tech should not replace these, just make sure they are clean. 2nd tri-metal bearing are for heavy loads as drawn cold steel shell is electroplated with copper to control thickness and the a high silica % and aluminum are heated, sprayed inside spinning tube with a precise amount to achieve thickness sometimes polished to finish fit. But the silica content is very hard and support higher loads over time and other types. You be happy now! Long time.
