Did the shop who machined it put in a exchange crankshaft? It’s either cracked or the bob weight figure is way off. Was it balanced? I had a shop screw up the bob weight calculation 1 time by figuring in 2 small end connecting rod weights. I would also make sure the flywheel & balancer is a non counter weighted style.
