The future of cam core metallurgy is here today! Now tool steel camshafts are more affordable than ever before! Callies metallurgy and heat treat teams have perfected revolutionary methods to bring you unrivaled camshaft durability. Callies Titan cam cores give you more options for performance enhancing geometry while increasing life expectancy. The superior stiffness of Titan tool steel works in your favor to minimize bending and torsional flex. Your entire valve train will benefit from the added stability Titan cores offer. Camshafts finished on Titan cores also offer extended service by allowing secondary grinding options when needed. Titan cores are available for most popular American performance engines.
