your piston rings came with the pstons are did you buy them alone ?
here is my rotating :
408
LY6 block
callies compstar 4" crank
callies compstar I beam rods
wiseco 4.030 pistons -20cc dished
target CR would be 9.3-9.4
pistons rings are what came with wiseco
bearings are king both main and rods
durabond chp23t cam bearings

I believe they came separately...
I sent LME the crank, rods and old block. I told Brian I wanted to reuse my parts and make 800rwhp with a turbo, and gave him complete freedom to pick the parts with the note to not spend a fortune. Its important to trust your machinst/engine guy, so I didnt have a problem not trying to tell a guy that has been doing this many more moons than me what kind of bearings to use.
You could probably get 900rwhp hp out of that. First thing to go would probably pushing gaskets with 20lbs+ of boost.
I keep everything in a spreadsheet so its an easy copy+paste
Heres the balance specs:
Balance Card
Rod Rot. 444
Piston/pin 535
Rings 36
Locks 4
Bearings 95
Oil 5
Rod Rec. 171
Total Bob Weight (g) 1734
