Stop in for a cup of coffee

Been looking up cams for OMR's engine and making a spreadsheet with the specs as some of the cams don't have all of the specs to enter into desktop dyno...

I found 4 cams with conflicting specs listed... The valve timing specs don't match the listed intake lobe centerline and lobe separation angle.... :BangHead: :icon_fU:

Trying to figure out what the correct specs are...

The advertised intake centerline is 102° and lobe separation is 107°, but their valve open and close calculate to 103.5° intake centerline and 105° lobe separation angle on three of the cams... :mad:

The other cam is off 1° on the intake and exhaust duration from advertised to the valve open and close information... :mad:
