I'm a little late on this, been outa town. One thing I learned during my A & P Engine class, Roller and/or needle bearings won't last in a large reciprocating engine. The compression and firing loads will flatten them if used in the big rod end. They may be O.K. to use on the crank, because the loads are transmitted through the length of it. I imagine they would work idf the engine is continually above 10K RPM, like my model boat engines. Although they are used in the small motorcyle engines, but there again the RPMs are much higher than in cars. Just thought I'd pass that info on.
