Another Chevy engine question.....

[Cranky]

I have a large journal crank (door stop?) for a 327 that's turned down .030 on the mains. Journals are .020 but are there bearings made for .040 under? I'm pretty sure it's going to need turning. Someone painted it thinking it was going to protect it but it didn't. Not in the Houston area at least. Summit shows this but doesn't specify for large or small journal that I can see.....

Called my brother, Chevy guy . We don't hold it again him but he takes his meals on the porch at family get together.
Anyhow, he said no to the .040 crank bearings ,
I asked if you could sub in a 350 crank , no again due to stroke and pin height.
You could go with the 350 crank but that would take new pistons the correct pin height.
He thought a large journal 327 crank should not be to hard to find.

I would not bat an eye at .040 crank. Guys turn crank mains and rods to whatever it takes. For instance RB cranks in B. Offset grinding rods to 2.20. I can’t help if thats a small or large journal bearing. Look for 350 .04 under bearings should be same as LG 327.
Edit: the part number you linked fits 350. So it should work on LG 327
