Improve your modified naturally aspirated drag racing engines with 308°/294° Stage 3 NA cams. Camshafts are designed to fit engines with ported heads, bigger valves, high flow intake and exhaust systems, and stroker bottom end with high compression pistons.

Our high performance cams work well with ethanol blend or methanol fuels, and you can keep NVCS/N-VCT variable intake cam timing with careful checking.

• Kelford Cams recommend KVS04 valve spring for best results.
