Rotating assembly for new style A-460 heads. Scat cast crank, Scat H-beam rods with upgraded ARP bolts, Ross pistons 13 to 1 comp. The rods, bearings, rings and crank have about 30 passes. Also 2 extra pistons. I was going to put it back together but have no time. The pistons are on the rods. I went to an A-460 block. 1200 or best offer.
