I have my engine in pieces and found out I need new rings and the bores need honing. Since everything has to come apart I guess I also need all new bearings to make the engine 100% again. My bearings looked good but I don't think they should be re-used.

What brand options do I have for LS1 bearings and rings?
Who's are the best, maybe OEM?
I have Katech rod bolts but should I also buy new ARP mains or just re-use the stock stuff?


Also, at this point what would the advantage be to going with a set of oversized, forged piston? This will make it a 347 right? I am never going to go N2O or forced induction so I doubt the forged stuff will help me.

Thanks

Also, what NOT to buy? I am curious too.

you were going to road race or run open track right?

if so i'd go ahead and get the forged setup. clevite, federal mogul, durabond all make bearings. diamond, JE, lunati make rings too. i think the best bet is rotating assembly; crank, rods, pistons, bearings, and rings. im sure any of the sponsors could set you up; eagle/diamond combo will be the best budget set. i'd upgrade to L19 rod bolts while i was at it. then have your block machined (line honed w/ tq plate), decked for straightess, cyl honed and cleaned, and get ARP main studs.

You need to be carefull with the main bearings if you going to if use the factory crankshaft.If you use hardened bearings with time they can your crank.If i going to use the oem crank i use the oem stuff.But i you use a forged crankshaft them use higend bearings.Just my .02 cents.

Sorry but I am not sure what you are trying to say? Something about aftermarket bearings being unsuitable for the stock crank?

Thanks for the info jrp, I would love to go forged but after looking at the prices for pistons and rods I am going to have to stick with all my factory internals and just get new bearings and rings. My guess is the best way to go is the 'ol GM dealer for OEM parts?

My local GM dealer tells me there are only standard size rings and bearings available for these engines. Does this sound right? I wanted to stay OEM because I have no idea about the quality of the aftermarket parts. Can anyone shed some light on this?

Federal Mogul 152M main bearings. Clevite77 H-Series rod bearings. Durabond cam bearings. All good stuff.

As far as rings go, anything from JE/Diamond/Wiseco/Mahle/Speed Pro/Total Seal will get the job done.

Wow, I went from zero info to too much info in one post Thanks for providing all those names.

Do you sell all these products? Which are the best rings for a street car?

Thanks for the tip, I will call them today. From the engine guys I've talked to it sounds like Diamond or Childs & Albert is the way to go for rings.
