I few years ago when I was researching for a cam purchase I did this. The specs are sometimes hard to compare because the Euros and the US measure timing at different valve lifts. And some post the lift of the cam as total valve lift after the rocker ratio is added, some post it as lobe lift. Just be wary of that.
As I recall, the exhaust lobes of my stock cam had a differential (lobe peak measurement - side measurement) of about .296 on the exhausts, and .310 on the intakes. That might help determine if it is indeed a stock cam. |
