The Edelbrock Rollin' Thunder camshaft #2221 is designed for 289–302 Ford small‑block V8 engines to improve low‑end and mid‑range torque while keeping a smooth idle. Matched to Performer manifolds for operation from off‑idle to about 5,500 rpm, it delivers enhanced throttle response. The camship includes lifter and assembly lube provisions; manufacturer guidance calls for a high‑stall torque converter and use of stock‑ratio rocker arms for proper operation.
