Pre-LS swap questions

[Root2812]

Well I haven't posted in the LS section in a long time per the above request but there has been a turn in my progress. My so called "good" engine was crap. It looks like it was left outside and got water in it. 4 cylinders were rusty. Its off to the machine shop for a bore and to get the heads done. I am hoping you guys can help point me to a quality full rebuild kit for a good price. I need new pistons and everything. The motor is a 2000 LM7 5.3.

I'll keep you all posted on the status of things. I hope to have it off to the machine shop sometime in the next month or so.
