Default Building a 408 and need help with my main clearance!

I had my eagle crank ground 010/010. The crank measures bang on the maximum spec. I'm using Clevite p series 010 bearings. The problem is my main clearance is 0.0015" I'd like to get some 001 extra clearance bearings but I can't seem to find any brands that sell a +0.001 clearance bearing for a ground 010 crank.

Does anyone know of any bearing companies that sell this bearing?

You might have to have the crank made a smidge smaller.
.0015 is in spec though, right?

That's within specs.

That's too tight IMO. You might want to check with the crank grinder to see if he can grind the journals on the low.
