LPE/GM LS9 Supercharger Cam

This is the GM factory 2009-2012 LS9 ZR1 camshaft that works excellent in many supercharged or turbocharged applications. The LS9 camshaft is 211/230 @.050 valve lift and .558/.552 lift with 1.7 rockers and a 122.5 centerline. 

Before the LS9 was introduced LPE used the GT7 camshaft that John Lingenfelter designed in 2001 to be the perfect camshaft for boosted LSx applications. The GT7 was 208/230 @.050 valve lift and .554/.546 and 121 center line this camshaft produced excellent power and still had great street driveablity. In 2009 GM introduced the LS9 in the C6 ZR1 supercharged Corvette engine. After comparing specifications on the camshaft and finding out how economical this is due to it being mass produced Lingenfelter discontinued the GT7 and started using the LS9 in supercharged or turbocharged applications.
