internally balanced 360 crank (BIG PROBLEM) need input

I thank you have a mopar hater balancing your crank . And he's probably a ford or Chevy lover and he sabotaged your engine hoping it would go out later . My 12 year old son can weld better than that . Make him pay for his mistake . And go to different engine builder to . Your engine builder should have caught that . The welds on the slug that's still in the crank look like **** !
