The cracked water jackets is my fault. I want to make this clear. My first human reaction to my discovery was to blame the previous owner assuming he knew of the problem and dumped it off on me (me having not thoroughly inspecting the car buying it on complete faith). But, I went to California and picked it up in December and it sat at my sister's house while I returned to Korea. Historical weather shows February 8th it got down below 22*F for a period of about 26hours. I feel like this was the moment that the block cracked.
Conclusion: My fault.

LS 5.3 pros:
Neutral balance on both sides of crank
6 bolt mains
World class ignition system
Lighter and more compact than 350/305
With a 5.3, all you need to is get the comp cam beehive springs, retainers, and locks and you have a rotating assembly that can go north of 7k but you are limited to 6k. It will last forever. The smaller 5.3 slugs and lowered lift cam means everything thing is understressed, then with a 260hp limit it's barely working hard.
Cons:
Oil control is a bitch, at a minimum you want a crank scraper and an accusump for extra insurance.
Valve covers are shallow so you have to do some worth with catch cans and a late ls6 valley plate to keep oil out of the intake. I got this locked down and adds maybe $200 to the build
Alternator needs an oversized pulley
Power steering pump reservoir can and should be relocated if you are using Camaro accessories

Truck accessories work much better with the third GEN and their dirt cheap!
