EVOLUTION 80 CAMSHAFTS
Andrews Products performance cams mean extra power for Evolution engines. H/D hydraulic lifters are capable of 6000+ RPM with stock springs and no valve float. Aluminum (T7) or chrome-moly pushrods (EZ-install type) are available to match any of our camshafts. Aluminum pushrods are lighter while the chrome-moly steel pushrods are more rigid for high performance.

 EVOLUTION 80 PUSHRODS, SPRINGS and COLLARS

 

Evolution pushrods are available with EZ-install ends or standard adjustable tips. Both types are made in anodized aluminum or chrome moly steel. EZ-install pushrods can be installed without removing gas tanks or rocker boxes. If you are installing bolt-in cams, this is a big plus!   High Lift Springs for Evolution engines-used with titanium spring collars, cam lifts of .550+ can be accommodated. Installation does not require head machining.

CAMS FOR DRAGS AND HIGH PERFORMANCE
For big engines (96+ cubic inches) or highly modified smaller motors and running compression ratios of 10.5 or higher, Andrews Products has high lift cams available which will put more usable power at the rear wheel than anything else going. These grinds are specially designed for highly modified motors.
 
  Installation requires expert knowledge and machining capability!
