What causes a rod or main bearing to spin? (not lacking oil)

His "edit" was spot on. Darin Morgan, formerly of Reher Morrison, would hone the rod big ends out of round (larger at the parting line, similar to how a bearing is eccentic) to prevent the parting lines from pinching in at high inertia loads/RPM. This has been a well known trick among the stock/comp eliminator crowds for decades.
Thanks and thanks for the info I did not know that, just fortunate to have worked/associated with some highly intelligent "car" people and learned alot.

The sounds engines make when they fail are very subjective. Groan, moan, squeal, squeak, scream, knock,etc. The list never ends. None of them are good, but once a bearing spins it doesn't make a whole lot of difference what sound it is making. You still have work to do.
