Curious cams?

[frank6969]

So I have a executive 175kw motor 4spd auto and I'm keen as to mod it some more, I read alot on here about cams from the states fitting these engines and being a good improvement but I've never seen any way to get them or what the actual improvement is? So I was hoping someone might be able to help with a bit of info if they have it.

Some info here. Though designed for the quad phaser cam.

Much better bang for your buck would be to go Kompressor (supercharged).
