I definitely want to explore the possibility of offering camshafts for the Duratec V6 engines. Now that more vehicles will be coming with these cams and more and more people are in the market for these cams, it should be easier to justify the investment from our point of view.
I can say that installing camshafts by themselves, as the only mod you do to the engine, can be a pretty expensive endeavor. Especially if you have to pay a shop to install them for you. Getting to the rear cylinder head in the engine bay can be a major pain in the A$$.
If you are building a 3.0L engine from the ground up and installing the engine yourself, not nearly as expensive $$$ wise, but time wise, yes.
