.030 over 340 - file fit moly rings - TRW forged 10.5:1 flat tops - may add 100hp nitrous shot - thinking .020 top ring/ .024 second from what I can find (.005 per in ) ?
rebel - stock type rings? I dont think you need to go that large. I normally go .004/1" of bore, and for 100-150hp of NOS that should be fine. If you want more cushion, go .0045. The rings on that piston wont get that hot...
