Re: some notes from a biggenr, change rings or change pistons?

Well you've got it apart. I'd break out the micrometers and the plasti-gauge. Check everything. New bearings would be a smart thing to do. Rings and oil pump too

All bearings need to be changed. They are cheap and you have it apart.

Have the journals of your crankshaft polished by a machine shop and check the clearances before buying new main- rod bearings. In case the crank needs machining, which is doubtful but possible..

Hone the cylinders and take measurements, honing is probably the only thing needed from the looks of the pics.

If you end up having to bore the cylinders then obviously you'll need new pistons, otherwise, re-use the pistons and get new rings.

Upgrade rod and main bolts to ARP fasteners while you have it apart. Head studs would also nice to upgrade at this time.

THIS.....

Re: some notes from a biggenr, change rings or change pistons?

I agree with what everyone has posted. Jarrod covers it well. No sense in short cutting it since it is out and apart. The oil pump is a weak spot. Contact Mahle and talk to the tech about upgrading your oil pump. They make a replacement that is more efficient and has higher flow than the stock LS pump. I found that out when I was at Joe Gibbs shop and talked to the Mahle rep that was there.
