I just ordered mains from Falcon Global Performance (along with other parts) and had to get -.010 as they don't have std in stock for my 62 394 starfire. I'm having the crank ground to suit -010 on both mains and rods. They should be the same for your engine.

Again no std size
I did actually ask Falcon when my project startet some time ago, he answered what std size was, which I found wierd , seen from my point of wiew (but to be honest I very rarely order engine bearings). But it doesnt matter as he also havent got std size mains.

Charlie Jones may have some sources. There is also Ross Racing Engines.....

No sense grinding a crank to fit bearings unless you have to. Good luck.

Standard size bearings are hard to find for almost any engine .
That's because anyone that re-builds an engine is usually going to need to grind the crankshaft at least .010 or more .
Unless your crankshaft is PERFECT and within .001 of factory specs for size , out of roundness , and straightness . I would recommend that you have it ground .010 undersize .

I already talked to Tony at RossRacingEngines, and he cant source them at this time.

Grinding .010 off a 394 crankshaft will not effect how the engine runs or horsepower, or you can keep trying to source them out and wait and wait and one day they might show up some where. But by that time you will have lost a year or some of the other parts that are laying around the shop. Grinding the crank and getting the engine back into the car so you can drive it might be the best choice here. On the block of some of the 394 engines is stamped an X or XX which stood for -.010 on rods and rods and crankshaft.
Just my thoughts as I tried to source std mains before having the crank ground.

Jan, my crank was perfect and didn't need grinding either, rods needed one journal ground so I had them ground .010 under and couldn't find stock mains so had to bite the bullet and have the mains ground too. Not what I wanted but the original main bearings were not to my liking so went with new. Now this engine will be as good as new and last my lifetime.

Would there by any chance be someone that would be able to look up, what the OE Oldsmobile part no. for the STD mains and rod bearings would be??
If not to much trouble, I would as always appriciate your help, as this would be a last call for me finding these bearings.

Std . 5458543
.0005 5458544
.001 5458545
Intermediate bearings ;
Std. 5458657
.0005 5458658
.001 5458659
Rear main bearing ;
Std. 5458324
.0005 5458325
.001 5458326
Depending on the amount of crankshaft wear , you may be able to use .0005 or .001 undersize bearings , If you can find them .
Good luck !

Correct me if I am wrong, but intermediate bearings has nothing to do with the rod ?? I am not confident with the word “intermediate”.

I appriciate your input, thank you for taking your time. It was a big help for my parts pusher, but unfortunently there where no bearings for me.
I will process the machining of my crank to end this project.
Have a nice weekend every body
