An very agressive option for LS1 powered vehicles without piston-to-valve clerance problems (with un-milled heads), and only recommended with a set of high flowing heads and a 4000 stall (auto). Agressive, but streetable in an LS2 car, and slightly milder in an LS3. Duration @.050 is 238/244, Lift is .605/.612, and comes on a 110LSA. PAC1519 will work with this cam but we reccomend one of the several dual spring kits we offer separate. Although stock valves should clear, we recommend checking piston-valve clearance.

Our cams are custom ground for us by Comp Cams. 3-bolt core is standard, but available in single bolt for newer GenIV engines. We also offer a 3 bolt cam conversion kit for those with an original single bolt LS3 who want to upgrade to the stronger 3 bolt design.
