Compatible with large-displacement 110" and larger engines with a 10.5:1 to 11.5:1 compression ratio, as well as 96" to 107" engines with an 11.0:1 to 12.0:1 ratio.
Profile with reduced overlap time and fast lift for increased cylinder pressure.
A slightly lower TDC lift makes installation simpler and easier.
Designed to perform optimally with hydraulic lifters.
Made in the USA.
The installer must verify spring compression, valve-to-valve clearance, valve-to-piston clearance, and cam lobe-to-crankcase clearance.
