I picked up a high mileage 240k lm7 that i plan on freshening up. Im going to roll new main and rod clevite 77 bearings in it. I am running stock crank, gen 4 rods for sure i may go forged on pistons however i have not decided. Im looking for 3.780 piston rings for boost. I have seen the seale power rings at 300 more or less but someone had told me about a hastings set. I am having a hard time tracking anything down other that one set. they are 1.5 1.5 3.0 rings that I am looking for. While i respect everyones research im hoping to here from someone running a car on boost that has had good luck and what they have used. I plan on doing 706 heads pac springs stage 2 sloppy cam for anyone who was wondering already have ls9 head gasket still need ls7 lifters
