Agree with your thinking Dave but it could be that Mountune developed their cam specifically to work with their long runner inlet manifold. Although they called it a fast road cam they might have tuned the cam profile, lift, timing and overlap etc to work with the pulses in their intake runners. (and the exhaust of course). Mountune are very experienced Ford tuners and do work directly with Ford on some special projects so maybe developed the cam with Ford.
That's an interesting and highly logical theory Bob, I'll call Mountune and try to speak with an engineer.
There are no Duratec cams offered on their website but they're clearly still involved with this engine, here's their 250hp Duratec build on ITBs.

Mountune also developed ECU calibrations on some of the Roadsters for Morgan / Powertorque

Interesting Bob, I never knew that, much like Cosworth, Mountune seem to be engine and engine management tuning consultants to OEMs like Morgan (via Powertorque), Ford, and others. My attempt to copy the Mountune MR200 kit has certainly given me a super smooth driving and torque rich engine with an additional 30hp over a standard Plus 4, throttle response is also massively improved.
All of this significantly enhances the Morgan driving experience I fell in love with when I first drove Monty, and all the evidence suggests there's still more to come
