Dyno Cams Camshaft 315 Grind, Welded Lobe, GX390, Predator 420cc

The 315 lobe design is the next step above our proven 308. With slightly more lift and increased duration, the 315 will make more top end power for an OHV modified engine. This cam requires an upgraded spring package, billet rod, and billet flywheel.
The lobes are welded to increase durability, extending the life of this cam.
