The COMP Cams complete camshaft kit for Ford 352–428 Thumpr hydraulic roller applications includes camshaft, lifters, valve springs, retainers, locks, valve stem seals, timing chain set and assembly lube where required. Intended for high-performance street use, it works with a stock converter but performs best with a 2,000+ rpm stall converter and taller gears, and yields a choppy, thumping idle.
