Used 4.5 cast crank, .030 over ross 13 to 1 pistons for A460 heads, scat steel h-beam rods with arp2000 bolt upgrade. I also have rings and bearings for this if interested. $800 pm me for more details. I also have a solid roller cam to go with this for $100, this combo with the A-heads made a little over 900hp in a stock block. Crankshaft and rods have no more than 30 passes on them.
