Yep new rings ,cam bearings, Rod bearings, Main bearings, Needs to be line honed,the cylinders need to be honed and probably would not be a bad Idea to also get the machine shop to deck it.
You may be better off getting a used one.
I would like to rebuild one just for the experience in doing so on a 3800 motor.
You can get rings from you're parts store or ZZPerformance.

is it not cheaper nowadays just to buy a new block?

Nah I have a block already I just wanted to know if I should replace the rings.

do a compression test on it and see if it leaks down badly.

I already have the block stripped bare. It goes to the machine shop tomorrow new cam bearings and main bearings are going in and the XP cam lol!!!!!

yea I am just ready to get in the car lol

new pistons would be ideal! rods hold up to anything! ever think about cryo treating the rods and crank? will add a crap load of strength!!!!!

pistons are still good I am getting new rings for them.

If your planning to go cammed (which i see you are) i'd definately build it right and go with some forged slugs. You might also consider increasing the size of your oiling ports on the bottom end.

why would you buy a used motor and not go into it is beyond me? i bought a used L32 from Ed and i still had it rebuilt. the car it was taken out from had 80k on it and the guy never changed the oil. there was so much carbon build up on the pistons etc.

I am getting everything new except pistons and rods but they are getting cleaned up and new rings. I don't need forged slug to just put a cam in.

forged internals wont take much more of a beating than regular ones if youre just going to let it slide because "you have forged internals". you still have to have the car running well.

Forged pistons are stronger without a doubt. 3800 Series 2/3 pistons are quite weak when making some power.
No, you don't need forged slugs with a cam. But down the road you'll probably want more and push your setups to the limits. The forged will undoubtably take more abuse (within reason) than the stock hypers ever will. Why build it now and redo it later? Might as well cover all the bases now, but thats just me thinking ahead.
Figured i'd point that out so you can look at your options. For the time and trouble, i'd get the forged slugs for the thicker ring landing alone. Not to mention the added strength.
Then again, no one chips pistons I suppose...
