I have always wondered why no one measures the crank & the caps, allow for the desired diametral clearance and make new bearings out of SAE 660 bronze tubing. Once they are bored to size, they could easily be grooved. No need to use insert bearings from another engine. The compressive strength of bronze would be better than babbit, Although one loses some embeddability characteristics, I think they would run fine for a long time. Naturally one would want a press fit on the OD of the bushing when the caps are preloaded.
