I've used them on various motors, but may I ask why the obsession with the Clevites? There's a bunch of bearing manufacturers that make competent bearings for many engines. If your crank has microscopic damage on the journals, it will
munch-up any bearing you install. I've used less popular bearings and have beat the oil out of my engines to prove the bearings worthiness in a well balanced and machined engine. Focus on getting your crank taken care and you can use whatever bearing your heart desires and achieve optimal results, even with the clevites
