The DI is more efficient than the MPFI because it atomizes the fuel more completely thereby making it easier to combust. What that amounts to is there is more engery produced from that fuel.

IMHO, right now, in terms of aftermarket support, the V8s have the advantage. A lot of what has worked on on past LSX engines can work on this one. The heads and intake are the biggest diversion from the LS1, however, the ports on LS3s are so huge that they rival CNC ported numbers from LS1/2/6 heads. In addition, I'm sure the LS3 is easier to work-on and modify because it's just a simpler design; it's not DOHC like the 3.6. The LS3 will always make better torque which'll move the car better.

I say, given your situation, if you can afford the V8, go with it. It probably wouldn't hurt to check out some LLT sites too if you haven't. I know there's a lot of untapped potential, but I admittedly don't know as much about that engine yet.
