The COMP Cams Hi‑Tech double‑roller timing set pairs a cast‑iron cam gear with an induction‑hardened billet steel crank sprocket and a pre‑stretched, heat‑treated chain. A 3‑keyway crank sprocket allows 4° incremental adjustability and up to 4° total advance/retard; the dynamically balanced set is quality‑checked for run‑out and intended for 1955–1991 Chevrolet 265–400 small‑block and 1978–1986 200/229/262 V6 applications.
