EVOLUTION 80 CAMSHAFTS
Andrews Products performance cams
mean extra power for an Evolution
engine. 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.
Notes on the cam listings below, please
understand that an EV31 cam is NOT
recommended for stock engines!
