274 (F200) Series: Radical Cam Grind for F200 Series and Super Box Stock
Approximately .274 lift and 260 duration. Square lobe design to maximize valve opening time. While meant to use with larger carbs, it actually works very well with smaller carbs by holding open the valve as long as possible with reduced lift to maximize velocity. Honda blocks may need clearance to install. Dual springs recommended (37lb will work, but will limit RPM to 7500).
Camshaft 274-1007: 9000+RPM. 12-to-1 or higher compression ratio required. Recommended for serious competition. Use for large ovals or where traction is a problem. Dual springs required.
