The COMP Cams CS 279T H7 nitrided Thumpr cam is a high‑performance street grind that delivers a pronounced, thumping idle and a broad torque curve. It can run with a stock torque converter but performs best with a 2000+ stall converter and lower gears. Expect reduced vacuum at idle; vehicles using power brakes may require a vacuum canister, pump or hydroboost to maintain assistance.
