X303 Cam question

[1Slow5oh]

I am contimplating which cam to install in my Stang. I plan on doing further engine work and i figured i would ask here first.. has anybody installed this cam into their 5.0 and how well does it work? Will I be ok with piston/valve clearance? And Is my current 2500 stahl enough for this cam? Any other suggestions would be appreciated.
