340 Engine Shake

UPDATE:

I lost the cam, it appears. There is shiny glitter in the oil and in the oil filter after he cut it open. So the motor has to come out and gone through. Super disappointed.
that sucks , seems it happens often these days , just hope my 340 don't suffer the same fate once i get it in the car , only has dyno pulls and break in so far , but with all the QUALITY parts on the market today who knows ?
You got no miles on the engine , who covers the cost of a rebuild ?
