I have used most of the popular brands and style bearing for the last 40 yrs or so. I use to only use race Clevite tri metal CL77 rod nbearings and the appropriate main bearing part # in most of my cars, I would use the Clevite babbit bearings(and still do) in stick shift cars. Once Clevite got bought out by Michigan and others subsequent holding companys I ended up switiching to the Federal Mogul and Speed Pro tri metal race bearings, I do use there HD narrow full groove truck main bearings in all of my motors along with the appropriate part number, usually BB Chevy , race rod bearings for the rod sizes I'm using Lots of choices out there, make your choice
