Best Engine Bearing brand ??

I've used King bearings a couple times, never had a problem. Same can be said for TRW/Clevite/Speed Pro, always worked fine. In fact, the only time I had a short bearing life problem, it was assembly buffoonery on my part, not the fault of the bearings.

I'm a big believer of full groove mains on street motors (as well as cutting in the oiling notch on rod bearings if need be).

Sealed Power 4092M is the part number for mains, and 62375CP for rods. Clevite "CL-77" type tri-metal. These are typical half groove mains, it would take two sets to make a full groove set.
