That's going to make good broad power. The downside, to me anyway, is the car will rock in rhythm with that cam. Kind of hard to describe but it's based on my experience with these engines. I can hear it in the lope. It's just something I have noticed with some cammed LSx engines from the beginning as compared to SBC's. I honestly don't know why the engines are more prone to doing that. I think it may be the firing order of the engine or maybe it's the fact that LSx engines can handle a much larger cam and still idle well compared to a typical SBC.

As for diameter, I'd go 3" with 1-7/8" primary headers unless packaging is going to be tight. Then you might look into 2-3/4" pipe. That might be a lot harder to get your hands on.
