Right now...the plan is do an iron block LS2 build with a stroker crank coming in at 408 C.I....but I may hang onto the notion of just leaving it a 6.0. I know iron block LS2 means an LQ4 but it will wear an LS2 upper.
And then of course I will supercharge it, probably with a centrifugal blower. I've always been jealous of the consistency my fellow supercharged buddies enjoy.
Transmission will be the 4L80e, certainly not the typical 3rd gen LS swappers choice, but the 4L60/65 costs far too much to make strong enough to last season after season.
The 4L80e will be the hardest part to fit in, with the mount being so much further rearward and that alters any notion of an easy bolt in Y-pipe out there to use.
