The COMP Cams CS 283T HR‑107 Thumpr cam is a high‑performance street grind that yields a throaty idle and stronger midrange power. Important: this cam is optimized for use with a melanized or nitrided distributor gear and is not compatible with untreated cast or steel gears; using the proper gear is required to avoid damage and potential warranty or return issues. It delivers reduced vacuum at idle.
