COMP Cams Camshaft Kit FW 291T HR-7 MT

If you're looking to build a high-performance street or strip Ford 351W engine, this COMP Cams Mutha' Thumpr Camshaft Kit (K35-601-8) is a solid option. This kit is designed for a range of Ford vehicles, including models like the Bronco, F-150, and E-Series vans from the 1970s through the 1990s. It's a complete package that gives you the core components needed to significantly change your engine's personality and performance.

This kit includes a hydraulic roller camshaft with a 235/249 degree duration and .552/.552 lift, along with matching lifters, valve springs, retainers, valve locks, and valve stem seals. You also get a timing chain set and assembly lube to ensure you have what you need for installation. For this camshaft to perform its best, COMP Cams recommends a minimum of 9.0:1 compression, a 2500+ RPM stall speed torque converter if you have an automatic transmission, and upgraded intake, gears, and headers. Expect a rough idle with this setup, which is characteristic of a performance camshaft designed for aggressive power delivery.

This is a serious upgrade for your 351 Windsor. It's important to note that this camshaft kit is not CARB approved and cannot be shipped to California. Make sure you have the supporting modifications in place to take full advantage of the camshaft's capabilities.
