Camaro/ Firebird/GTO/Corvette SLP Oil Pump 97-2005 LS1/LS6 Heavy-Duty , Stock LS1 oil pumps have been known to fail without provocation, causing extensive--not to mention expensive--engine damage in the process. To prevent this, SLP has developed a ported-and-blueprinted pump that is virtually bulletproof under even the most severe racing conditions. Surprisingly affordable, it's an ideal complement to our Double Roller LS1 Timing Chain (#55000).
