308 Grind Welded Lobe Cam Shaft for Zongshen 625

308 grind welded lobe race cam for the popular Zongshen 625cc single cylinder engine ground by DynoCams in North Carolina. Guaranteed to rock your world, this camshaft is more aggressive than the CS and CM cams that we offer and will make more power at higher engine speeds. The valve lift with stock 1.45:1 ratio rocker arms is .447", and big block clone springs do fit the 625 cylinder head, so we recommend 65lb dual springs, a billet rod, and a billet flywheel. Torque peak of a combination with this cam comes in around 5200rpms and it will thunder up to 7,000rpms fast, so use at your own risk.  

*Keep checking back with Big Block Clones because we have performance parts coming for this engine!
