EVOLUTION 80 ENGINE CAMS

Performance cams mean extra power for Evolution engines. Hydraulic lifters are capable of 6000+ RPM with stock springs and no valve float. Aluminum (T7) or chrome-moly pushrods (both fully adjustable) are available to match any of our camshafts. Aluminum pushrods are lighter while the chrome-moly steel pushrods are more rigid for high performance. Titanium spring collars will fit stock keepers and springs.
