It appears we can not get these bearings from Clevite or KIng . Called KIng and was told maybe in May. Clevite said I can order but would not give me a date. 

Zmotorsports does not have a date either. Z car depot can not get Clevite.

So are there any other brands that are good?

The engine had been built by Slover porting in Sun Valley Ca.  L28 valves with steel seats, l28 crankshaft and punched out to 85mm

Evidently bearings have been difficult to get for a while. Search on Ebay if you know what part number you need

Try calling some local machine shops. The older the business the better.

What, if any, is the oversize you need?

rockauto.com shows standard 280 bearings, Sealed Power for the crank $66.

Out of stock on the rods.

Im looking for .25mm (.010). Good idea with machine shop. I will look at rockauto. Thanks help

I ended up using part numbers from rockauto to search Ebay

I have some new King bearings I will not be using.  I'll check tomorrow for the undersize.

Thank you

I was able to put my hands on the rod bearings with relative ease.  I'm still in the middle of moving everything into the new shop, so it's a bit of a cluster.

If you need mains, lmk and I'll look more.

I purchased main bearings from zcardepot.  If you would like to sell rod bearings give me price. Been moving to a larger shop so I know how that is

 

Sorry, just circling around to this.  Yes, I am happy to help.  Let me see what they cost me and then I'll PM you.

Are you in a hurry?
