See if you can find someone to do a rockwell test on the trunion. Any good metal shop should be able to do this. If these are cheap (chinese) knock offs, you found the problem. Lots of crap out there these days. Ive seen brand new cranks with indexing off +.010" and journal roundness out by over .002" right out of the box. Basically unuseable until its correctly re-machined. Lots of engine builders just bolt them in as is. Lots.
