I think .0015-.0020" press fit would be OK and the heat/cool installation method will work OK but, in an ideal world, the best way to final size the ID of the bushing is not to hone it but to burnish the inside by pressing a correct size steel ball through its bore. This not only sizes it but expands it against the rod bore much like installing an intermediate shaft bushing.
Living in Peru and playing with old musclecar engines, far from an ideal world!
So I guess I will go with 0.002" interference and the heat/cold method. The machine shops down here dont have burnishing tools, I asked at several and they dont even know that tool exists. Reconditioning some old rods from a rotating assembly thats already balanced to those rods. I have other engines with H beam rods and brand new internals, just not this one. Just trying to make things work and not end with a time bomb.
