FEULING OIL PUMP CORP. Conversion Cams - 525 Series - Twin Cam 1016

If you're running a stock or mildly modified Twin Cam and want to unlock real-world power gains without a complete top-end overhaul, the Feuling 525 Series cams deliver where it counts. You'll feel the difference immediately—sharper throttle response, easier cold starts, and a wider torque band that makes your engine pull strong from idle through mid-range RPMs. Best of all, this is a true bolt-in upgrade that plays nice with your factory valve train.

The 525 Series excels in both 88" and 96" displacement engines, and if you've already invested in a 103" stroker kit or upgraded cylinder heads, these cams will reward that work with noticeable performance gains. Whether you're chasing fuel economy, better rideability, or both, this is the kind of straightforward, no-nonsense upgrade that separates serious builders from parts-bin shoppers.
