This is on my to do list as well, I already have the extra intake and LS2 TB on hand. Gwatney will be getting the intake for the rod mod and porting, Vmax for the throttle body, and I still need to order the parts from rotofab and the LS7 MAF. I have heard mixed reviews from others that this is not really a cost effective improvement for our cars. But I'm sort of at that point where I need to either increase displacement or go FI.
So I figure why not do it and see for myself. I will post up my findings when I get it done just so others will know. Give me a couple months to get my **** together.
