This past weekend I was discussing bearing failure that we were experiencing in a BB MOPAR with a well known and respected racer/machinist/engine builder. This gentleman has forgotten more than most of us on this site know.
He suggested that we groove the main journals for more oil flow as he has been doing for some time. This in addition to full groove mains.
I questioned the strength of the crank. He was very convincing in his explanation. The car he is currently running is a stunning SS ride that is turning a BB mopar 8000 plus and lives.
I've been in this sport 30 years, and have never encountered anyone doing this. If anyone else had told me this, I would have called for medical help. This racers background lends total credibility to his ideas.

Anyone else doing this?? Lets hear it.

RIP
