King Bearings?
Putting together 2 350 strokers for groceries (no racing).
I usually select my parts 1sies and 2sies.
This seems like a pretty good deal:
These Eagle street performance rotating assemblies offer the perfect balance of strength, performance, reliability, and affordability. They include a cast steel crankshaft, Eagle "SIR" I-beam connecting rods, Federal Mogul hypereutectic pistons, Perfect Circle rings, and King bearings. The kits are only available balanced. Eagle street performance rotating assemblies are the perfect choice for engines up to 500 hp.

Does anybody know who the heck "King" (bearings) is?

They have a pretty good rep. They're not Clevite, but for your app they will be more than satisfactory.

Also take a look at some of the rotators that Competition Products sells.

King is made in Israel, they have been around at least 30 years. They are a low cost provider of bearings, My experience has not been updated since 2004 but at that time the King bearings tested were about the same quality as mid 60's technology.
Either Clevite or Federal-Mogul offer much better quality but cost more.
I will qualify that my information is old, I could make a phone call and find out how true this is today.
The bearing industry has evolved, in the 60's very few engines ran over 100,000 miles. Today all engines are expected to exceed 250,000 miles.
Unless it is a bad engine design or the OEM decided to buy import bearings (Chrysler 2.7L rod bearing failures). Keep in mind the bearings are doing this while providing service with much more horsepower than they made in the 60's. In Example, 1970 LT1 370 HP, LS7 525 HP, if tested to the same standard the LT1 is probably only a 300-325 HP engine. The new designs can handle much better Horsepower and do it with more than double the life of the old bearings. I will have to check and see if King has upgraded since 2004.

I've been buying Iscar (Israeli carbides) and Shaviv cutting tools for about 25 years. Both Israeli mfg. If the King bearings are as good for the price as those, they will work just fine. They are about a mid range piece, and should serve well to low 500 hp.

Pending the answers to a few questions submitted to Summit, I will probably buy the Eagle kit, but I already have several sets of Clevite bearings in stock. The problem is, the kit is balanced with the King bearings. I'll have to compare the weight of the King shells vs Clevite when I choose.
Thanks for the input.

Nope. Not kidding. I have been building engines since... 1965... and have come across some oddball bearings. They are not all the same in construction. Materials vary. The bearings should be nearly identical in weight but I won't judge until I have both sets in my hands for comparison. I honestly don't anticipate any issues.

My first engine was in '66 so ya got me by a year.
Best of luck with your build.
