I just checked all my Molnar rods this weekend. All pin bores were with-in .0001", all rods with bearings installed were +/- .0002" but I did not measure the rods and bearings separately. Clearance depends on what your crank is. Mine would have been .0021-.0022 with a standard 2.2000" journal with a coated Clevite 743HN CL77. I have no idea how thick the coating is as they were done before I received them. Total weights were with-in .9 gram except one 1.4 gram.
