webcam camshaft 149
We are trying to time the cams on a 2.2 S motor with a webcam #149 camshaft. We assumed the grind is equivalent to a Mod S grind...but want to make sure. The valve lift on a stock S grind is 5mm vs a Mod S at 4.5. Can anyone help with identifying this camshaft and the correct lift? Thanks guys.

Set the #149 grind at 5.2mm to split the overlap. Its a modified S profile.
Intake lift: .450 Exhaust lift: .400 Intake duration: 264 deg Exhaust duration: 236 deg Intake LC: 96 deg Exhaust LC: 100 deg
