Product Details

COMP Cams is well-known for making performance engine parts, and their Magnum series camshafts are a popular choice for drivers looking to get more out of their Ford Small Block V8. This particular camshaft, the FS 270S-10, is designed to give you noticeable performance gains over your stock cam without being overly aggressive on your engine's valve train components. It's a solid option for daily driven performance vehicles that need a bit more power, especially if you're running a higher compression ratio, around 9.5:1 or more.

You can expect this camshaft to deliver strong power up in the higher RPM range, making it a great companion for an aftermarket torque converter with a higher stall speed, around 2000 RPM. It balances performance with good driveability, meaning your truck or muscle car will still be comfortable to drive around town. While it offers a mild, performance-oriented idle, it's built to work well with mild ratio rocker arms and traditional performance valve springs, making it a straightforward upgrade for many Ford 221, 255, 260, 289, and 302 engines.
