The COMP Cams C43 280H-R10 retrofit hydraulic roller cam suits 1985–1987 GM 4.3L (262 cid) V6 engines originally using flat tappet cams. Intended for limited high‑performance street use, it produces a mild rough idle and performs best with an aftermarket intake, headers, a 2,500+ rpm stall converter and 3.40–4.10 gear ratios.
