I take a fair amount for granted, just cause...
After the cap grind, the rods are machined/honed to be perfectly round, they hold the bearings just that way... At the parting line, there can be an unfinished area, as much as 1/8-3/16", the to ME does not make a bit of difference... When the engine runs, most of the load is compression, and a bit of pressure the other way, as the crank pulls the piston down for the intake... A lot less side loading, (at the parting line)
TRW rods were just about the same price as shops charged to rebuild a customers own cores, and as I remember, their cores could be pretty wide ranging in terms of relative weight and quality...
(I'm grateful not to be in THAT buss anymore)
