Question Federal Mogul (sealed power) bearings.... good or bad?

Are these good bearings? I can get them for relatively cheap ($64 for rod and main bearing together), but if they are not as good as clevite's, then I'll go with clevite. Any suggestions?

I prefer to use (2) sets of Clevite 77 Tri-metal bearings for fully grooved main bearing inserts, along with the Federal Mogul rod bearings. These bearings are a softer material that the Tri-metal bearings. They work very well for rod bearings. If you have the rods resized, magnafluxed and shot peened, and use ARP or other high tensile strength rod bolts, you will have a reconditioned rod superior to the factory new replacement rods. If you go to all this trouble though, you might want to go ahead and have the machinist pin the rod caps and drill the lower rod insert to fit on the pressed in pin. This will prevent a spun bearing from occurring unless there is catastrophic failure of the rod, rod bolt, or bearing insert.

I'm sure it really doesn't make a bit of difference. It's not the bearing that matters, but the layer of oil that the part is riding on. My personal preference is Clevite. You can get rods and mains at Autozone for $65 as well. I couldn't find any Clevite thrust washers in town, so I got Federals from O'Reilley's for $10.

Here's a pic showing both rod bearings side by side. The oil hole on the Clevite is SLIGHTLY larger and is dished out a bit.
