Default ls1 or ls2 throttle body

I was wondering if there is any advantage to running an LS2 throttle body over a LS1 throttle body on a FI vehicle other than the four bolt pattern rather than the 3 bolt ?

Power can be made with either one...what are your goals?

my goals to start are about 700 at the wheels with room to crank up the boost... the throttle body is going on a 468 big block and will be running an F1 series procharger most likely when i get everything done, but its also going in a 6000 lbs truck so i need to compromise between the low end torque and hi end power.
