Emissions Legal (CARB EO #D-250-2)
NOTE: Modern hydraulic roller camshafts typically experience valvetrain instability at approximately 6200-6400 RPM because of their fast ramp rates. We suggest you upgrade your valve springs to AFR part #8605 or one of our PAC racing options with higher spring pressures. All out racing applications should consider using AFR's patented “Hydra Rev Kit” to reduce chances of valve float associated with 6200 or higher RPM ranges.
