Well for starters the lift is not much over stock.

Stock "theoretical" valve lift is ~9.80mm (vs 10.15 to 10.70)


Also you still DO NOT have the valve points. Intake/exhaust open & close. While you have the duration of each cam you can not nail down the rpm range and curve size without knowing WHEN it's actually happening.

Stock duration
Intake Primary: 244
Intake Secondary: 250
Exhaust: 260

SVT duration
Intake Primary: 250
Intake Secondary: 258
Exhaust: 262


For instance the SVT cams have more duration then stock, but NONE of the valve timing points are the same. It's not X extra duration from a set point or even in the middle of an equal number of degrees from each point.

Valve timing is everything! Every point plays a large part. How close to TDC it opens, how late after BDC it closes, etc, etc and vice-versa for the exhaust cam.

Using just a generic duration is very inaccurate.
So is your thinking about comparing a single cammed pushrod 2 valve engine to a DOHC 4 valve engine. The changes on a DOHC engine would be much more drastic in effect.
