It's all apart. Right around 200 passes since the rod bearing failure. New crank, rods, pistons, jessel belt, valves, locks, springs, valve job, new lifter bushings, rings, bearings, crank scraper, and oil pump guts. In my notes on the build at the end of 2021; " #5 intake has a pit in the lobe. " Apparently the heat treat on the surface has degraded further. The current cam has 1718 int and 1862 exh lobe on 112 lca, 4/7 swap. The cam in hand has 1719 int and 1864 exh on 111, std firing order. So .022' more int lift, 4 degrees more exh duration. Same lobe designs. The lifter wheel apears to be undamaged. I'll check but it had tons of piston to valve and some room left on coil bind as well.
