Default How hard is it to rebuild your own lsx?

Well I found out that I spun a bearing and was thinkin about rebuilding the motor myself. Any people done this? Looking for some input and pointers. I have built a 383 stroker myself but not an lsx motor before. Are there any web sites that will help walk me through this.
My plan is to keep everything the same just turn the crank and put some new bearings, probably an oil pump cause I have a feeling this is why Im in this situation. I have lunati billet rods and diamond pistons that I would like to reuse if possible. I will have the rod ends checked to make sure there not out of round.
Can you guy's think of anything else?
Is doing it myself a bad idea?
Thanks
Brian

Are they cracked rod ends. If so, what do you plan to do if they ARE out of round? It's not like you can resize them.

If youve already built an SBC, why not step up to the LS1. As long as the machine shop checks everything out and all you have to do is reassemble.

i say go for it. Just like said above, have the machine shop check it all out, then reassemble it yourself.

Looks like he is going to build the ls block he just wants to know how much different it is from building any other sbc.. I would say its just about the same. Pick up a haynes manual and they guide you through alot of it and it tells you the proper ftlbs of bolts. Just make sure you don't the cylinders don't get bored out too much. Just a hone is what you should need!

Yeah, I would like to keep the pistons I have cause I believe that the bore is maxed out anyway (3.905) maybe someone can let me know. Im also not sure if I can just clean up the bore and buy a new set of rings without running into clearence issues.

if your going through the trouble of taking it apart spend the extra money to get forged rods and pistons. even if stock compression, just having it there for later is worth the expense than doing it twice

The max bore on your engine should be 3.910.
