Cam specs for Ported Heads - ZR-1 Net Registry Forums

XfireZ51 · 04-04-2010

As I have followed Todd's exploits with his 427 and interesting cam profile,
it occurred to ask whether the stock cam profile is optimum for the additional airflow available through ported top end and heads? Not sure how much more airflow a set of GVD heads provides, but it would seem logical that using stock cams doesn't exploit potential of the added airflow. Is it a matter of degreeing the cams differently or require a cam regrind to add more lift and/or duration?
