[DeTomaso] Weirdness with my Cleveland ...

It has been pointed out and oft repeated, but I suspect it is Pantera folk lore.  I have been running a HV pump without problems for a few years including some track days.  I have never heard anyone say they sheared a pin due to a HV pump.

It has been pointed out, in the past, that running a  
high-volume/high-pressure oil pump will almost surely shear the pin in  
any kind of racing.  So if a double-pinned gear was still shearing,  
I'd start looking for other problems.
