ZL12 Hyd. Roller Camshaft (3-5 WEEK LEAD TIME)
Designed for 6.2L and bigger and 11.0 to 1 and higher compression, this cam is begging to make some serious power. 228/231 duration is streetable but gives a pretty choppy idle and an aggressive mid to high rpm power band. The .580"/.590" lift numbers require our 6.vsp510 valve spring and piston to valve clearance must be checked. Pistons may require modification or aftermarket pistons. Hardened pushrods recommended.
