Clevite MS667HX main bearings
I'm rebuilding a 455 SD for a customer and the new Ohio crank I bought for it is fat, and on the high side spec wise I'm looking for an extra clearance bearing for the 3.25 mains and the only one I see are the Clevite MS667HX. As with everything else these days no one has any. Do any of you have a set, or know off a place that has some in stock? I checked with Butler, KRE, Summit, and Clevite. All out

Can you polish the crank down some to spec?

Jeg’s is showing a set.

No businesses have them.
Does anybody have any in their collection of parts they would be willing to turn loose of? MS667HX Clevite |

Do you have any Bearings with a gray brake in coating that?
If you fine scotch brite that off with the aid of a very light oil that could give you a added .0015”. Many builders do this . |

The crank is .0002 under the max. I calculated if we align hone the block, and put it on the max, I will have .0018 clearance. That's using the Sealed Power bearings which I actually measured. In my experience Sealed Power bearings measure thinner than Clevites. I don't feel comfortable with .0018 on an original 455 SD engine/car I'm shooting for .0023 -.0028. The pistons for it are going to take 10 weeks so I guess I'll see if Clevite gets the extra clearance bearings in stock between now and then. If not, I may take it to a crank grinder in town and see what he can do. Scary!
