Default C5 Z06 engine swap to LS3 or LS7

I've been trying to do my homework, and it appears a lot of people like the LS3 motors for C5 engine swaps. I'm not sure I understand why it's so much better? The LS7 makes the kind of power I want to boot with an extra 0.8L of displacement to work with.

My '02 C5Z is becoming an almost dedicated track rat now (still like driving to car shows). Besides more power output, I'm mainly concerned with getting the dry sump system to go along with it, so C6 Z06 or Grand Sport donors are my goal. I'm aiming to get a running engine from an insurance auctioned C6, and part out and sell what I don't need to recoup some costs.

I know there are a couple concerns about the reluctor wheel and other sensors, but I've seen some companies selling all the proper equipment to integrate the C5 PCM with a Gen IV LS block. I also know I'll have to get a battery relocation kit since the dry sump reservoir will need to be fitted where the battery currently is.

The C6 GS has a cooled transmission setup that would be awesome to entirely swap into my car too. Can the GS transmission easily be swapped into the C5? Does the C6 Z06 have that (T56 and T6060)?

Is there anything else I'm missing? Thanks, everyone!

I have an upgraded Ron Davis aluminum radiator as well. Is that compatible with the LS2/3/7/9 Gen IV motors? Will it be enough to handle the thermal load with a 450RWHP or so load for track days?

There's a guy on here, his handle is MAXX, in the c5 section. He put an LS7 in his C5 FRC. Look him up, I'm sure he has all the answers.
