Oil Pump Shafts

Oil Pump Shafts..Responsible for driving that oil pump, there was a problem with the 5.7 where the Oil Pump shaft would fail, rounding off the hex on the drive ends or snapping completly in two...Uh Oh!..This obviously means that OEM is not good enough. Mondello Performance has a Billet Oil Pump Shaft (part # OD260)for about $20 plus shipping...Is noticably stronger and weighs more. I belive that Dick Miller Racing carries a similar oil pump shaft. For use on high performance Oldsmobile gas engines, a superior oil pump shaft makes a good little investment when building a motor, or replacing an oil pump...You wouldnt want to loose your engine by trying to save an extra $20 would you???
