Shoot holes in this idea for me. I currently have a '98 C5 with a very stout, Procharged 427 (C5R block, bulletproof rotating assembly, LS7 heads, etc. etc.) but now want to upgrade the driveline to a TR6060, C6 Z06 diff, and at least C6Z brakes. The tab for buying all those pieces will run over $10k. Since I like the looks of the C6Z better, should I consider finding a healthy Z with the TR6060, swapping in my 900+ RWHP engine, putting the stock LS7 in my (low mile, pristine C5) and selling it. Fire away!

Yes.

However you may get more money if you sell the LS7 separate and your c5 as a roller.

One of the biggest questions I have is around your time. The plan sounds fine, but is it worth your time to do all that? If you aren't in a hurry, can wrench on it yourself and enjoy it then go for it. If you had a shop do all the work, there's no way you would come out ahead.

Early or late crank trigger? Not compatible between the 2 platforms. You can use a converter box to run the early management with the late motor, but far as I know, no one makes an adapter the other direction.
Otherwise, pull the crank, change the trigger wheel...
Aside from that possibility, I think updating to the whole car instead of just the pieces is a great idea!
Probably most cost effective just to replace the C5 engine with a used LS1 and sell the LS7 separately.
