455+.030 Hyper pistons, rings and stock rods. I think these pistons are Speed Pro #H392HP. I bought them new, but have misplaced the paperwork. I polished the beams on the rods and had ARP bolts installed. These were mocked up in a block, but then I decided to go a different direction, thus they've never been run. $250 plus shipping. Thanks BILL SR
I think the comp ratio is in the 9.5-10 range. There's a # on them, H392NP, so it appears that they may be Speed Pro. Thanks BILL SR
