The ultimate in high performance, made from aerospace grade 8620 steel billet material and CNC ground on state-of-the-art cam grinders, our Signature Series Camshafts deliver the utmost in rigidity at extended RPM range while reducing possible valve float. 

Through rigorous testing we have seen 10-15WHP gains on NA setups and  50+WHP gains on forced induction applications, completely stock engines. With increased compression ratio / stroke / bore size you can expect to make even more.


The stage 2 camshaft is most frequently chosen and paired with K20 bottom ends. The stage 3 & 4 camshafts we typically recommend for K24 bottom ends (stock & fully built). This camshaft profile has an emphasis on mid-range response while providing excellent top end flow. We suggest our K20 auto-x / dirt track / time attack drivers to utilize this camshaft & wake up their powerplant.


My own personal K20A2 longblock made 703WHP @ 25PSI utilizing the prayoonto stage 2's. Dynograph shows no leveling off even after 9500RPM. The engine still capable of producing more HP but my fuel system was maxed out.
