Larry try the King CR807XPN bearings. Very consistent thickness. Better than clevite's.

And I'll add that I see less "delamination" with the King over the Clevite when they've been pounded.

I think I have King's in the pink car. What ever is in there its goin on its third season.

I received a new set of CB663xxx and they are good enough to install in a rod and check for clearance. Each shell got checked six places along the part lines for thickness variance and recorded in the Dumbo book

What did you see for differences?

Larry Hill · 03-04-2022, 08:54 AM

Out of the 96 places checked .0588” to .0595”, so thick to thin was .0007 and no shell had a variation of more than .0004.
Now they will be installed in the rods and checked for vertical clearance and taper. If all of that is ok Dumbo will have a fresh set of bearings.

Hats off to the real engine builders that have to fight this kind of stuff on a daily basis.

Did you also order a set of King's? You may be surprised at the difference. I won't say that they are the cat's meow, but I like what I see when stuff comes in for freshen ups. The Clevite's are probably good enough for 85% (or more) of the engines out there, but I usually see better consistency with King, and sometimes ACL, depending on application.

I have two CB 663's and one set of ACL so I should be able to get something to work. If not I will get a set of Kings

Got the pink car running yesterday after it being rewired and with all new Classic Instruments gages. I think we solved the occasional no start problem, a bad fuse block. For some reason I had another one on the shelf.

100 percent correct on King bearings
