Product Details

This is the COMP Cams FB 306S-10 camshaft, designed for Ford FE engines like the 352, 390, and 428. If you're building a pro street machine or a serious performance street rod, this camshaft can give your engine that aggressive, radical idle you're looking for. It's a solid lifter camshaft, meaning it requires a bit more attention during setup and maintenance compared to hydraulic lifters, but it's built for high-RPM performance.

This camshaft is intended for applications running a 3500+ RPM stall torque converter or a 4-speed manual transmission, and it works best with an 11.5:1 compression ratio and lower gear ratios. These specs indicate it's meant for a performance-oriented setup where you want strong power delivery, especially at higher engine speeds. The 'FB' in the part number signifies it's part of their 'Ford FE' series, and the '306S' designation points to its specifications, including its duration and lift profile, which are optimized for aggressive street performance.

When installing this camshaft, remember it's a solid lifter design. You'll want to ensure your valvetrain is properly set up, including valve lash adjustments, to get the most out of it and ensure reliable operation. This camshaft is a popular choice for enthusiasts looking to extract maximum performance from their Ford FE V8 engines.
