Sorry. I misunderstood. Speed reading doesn't always work!
The smaller cam is probably a better match for your other parts. It will make peak torque at a lower RPM, and probably even more torque. It will give up horsepower at higher RPM, I'd guess 4500 and up. The engine should get a little better gas mileage, too.
But, hey, if you like the current cam, keep it.
Vortecs do have their problems, but flow better up to approx .500" lift than any previous cast iron production head. And they really shine at mid-lift where the valve spends half its time. That said, I have a pair on my truck's 350, but would do something different next time.
