Small journal crank into large journal block???

Well I have a small journal (2.30)main forged steel crank and its goin in a 400 block that has (2.65)main and I found journal spacers and adapters to go from the med 2.45 to the small 2.3 journal and the ones to go from large 2.65 to med 2.45..... my problem is i cant find any that go are thick enough to put my small journal 2.30 crank into a large 2.65
Anyone know who sells an adapter or spacer??? or know another way of making this work?

Never have tried it, but I wonder if you can stack 'em?

use the spacers for the 400-350 size and then use the spacer bearing set from the 350-283--

if you need the bearing part number let me know and i will look it up

don't think I have any of the bearings and if i remember correctly they were maybe only avail in std and .010 under
