Welcome to Bulltear!
I think this discussion has come up before. .040" bearings for the 390/401 may not be available. Last I heard, King Bearings had some in stock, but weren't planning on making any more.
Have you thought of having the journals welded and cut back to standard?

Yes you will have to get them to weld up the crank. Then go .010 because std bearings are not available anymore.

Car Craft did an article a couple of years ago. They got 484 HP and 500 ft/lb of torque on pump gas.
You may be able to cut the crank to 2.1" rod journals and use Chevy 6" rods, and custom pistons. The mains would still need to be welded up.
