SLP Camshaft, LS1/LS6/LS2 Hydraulic Roller (Call for specs) This is our most aggressive camshaft for LS1/LS2/LS6 applications. Designed to produce maximum power in big-cube stroker engines, it also works well in moderately to extensively modified stock-displacement applications. Includes detailed installation instructions and guidelines for proper degreeing. NOTES: SLP High-Performance Valve Springs (Part #53002), Retainers (Part #53103), and PCM reprogramming strongly recommended. LS6 or ported LS1 heads recommended for optimum performance. This camshaft has a 3 bolt core and will only work on a 3 bolt cam sprocket. 2007 and later LS2 engines have a single bolt core cam and cannot use this camshaft.
