Obviously, I don't know what your engine has in/on it, but if you were 
running any of the three possible stock oil pans and tires wider and stickier than 
OEM (which is everyone in the world), your situation was almost certainly due 
to the cornering capability of an average Pantera causing all the oil remaining 
in the pan to slosh away from the pump pickup. This momentarily starves all 
the bearings in every turn. In addition, its well known that under higher rpms 
in a straight line, about 1 to 1-1/2 quarts of oil are trapped in each   
rocker cover, leaving precious little lube down in the pan. 
The obvious first move is to replace the pan with a larger oil capacity, 
fully baffled unit, and not a cheap drag race pan either. Most Pantera owners 
interested in performance have changed to the Aviaid or Armando pan, and 
magically, bearing failures no longer occur even in dedicated track cars. Whether this 
is a 'design flaw' in the 351C's oiling system or not is up to the consumer, 
but 30+ years of experience says if you own a Pantera, change your pan first- 
even if you never get close to a track! For at least the last two decades, 
reputable engine builders familiar with the Pantera will not sell an engine & 
warranty without a fully baffled, high-volume pan mounted. 
My best guess- J Deryke
