Main Bearing Fits Loosely in Billet Main Cap

[WE2Regal]

I've got a main bearing that doesn't fit tightly into a billet main cap. It doesn't snap into place like it should. There's no play but it's loose enough that when you turn it over, the bearing just falls out. Tried other bearings and they fit the same way. The cap is a newer one made after Pro Gram Engineering was sold to Billet Speedworks. Is this bearing just going to spin on startup?

Aftermarket caps need to be fit & honed for bearing crush & main clearance.

The block and caps were align bored. The bore was checked and in spec.

Are you measuring this yourself or is someone telling you it’s in spec?
