It will be interesting to see how the white metal copes with the pitted crankpins, but oil films are much thicker than in moderns.
If you reuse the pistons dunno where would get original wide rings, unless someone has some used slightly oversize. Does anyone still use? On my car acheived both neglegible and colossal oil consumption with these. Many replacements were too thick and stiff and caused accelerated top groove wear. A very slight shallow chamfer on the top edge often assists low oil use.
My father ran our RP from 1940 to 1960 and met many people familiar with the cars. He had great faith in the car and never heard of broken cranks. Later when I ran it several asked me if it had a 3 brg as these were apparently notorious.
