The Edelbrock Rollin' Thunder camshaft #2231 is specified for 283–400 small‑block Chevy engines and targets stronger low‑end to mid‑range torque. It pairs with Performer manifolds for use from off‑idle to 5,500 rpm and delivers smooth idle characteristics. The cam has defined duration and lift specs and must be used with a thrust button, high‑stall torque converter and stock‑ratio rocker arms only. Dyno pairing examples show substantial crank output when matched to supporting components.
