Crow “NEXT GEN” LS camshaft profiles use a totally new CNC master generation system to produce cams with higher lift and larger 200” duration figures for significantly more power and mid range torque. Next Gen profiles high tightly controlled rates of acceleration so that spring and valve train bearing life is not compromised. Special attention was given to designing effective quieting ramps so that excessive valve train noise is not generated.
Crow Cams have also introduced profiles specifically suited to the high flow rectangular port L98 head with much larger duration spreads that shops are having success with in VE builds.
A new Next Gen valve spring has been developed in association with PAC Springs USA to match the new range of camshaft profiles. The new 4919 spring has PAC “Nano Gold” surface peening treatment similar to PAC drag race springs that minimizes load loss and stress at high RPMs. It has slightly higher pressures than the popular 4918 and will comfortably handle .620” lift covering all the new Next Gen profiles.
