WHO KNOWS STROKER MOTORS ?

Bought a 408. Im taking the guys word for it. I did hear it run & it sounds really good. I would think that if your going to build something like that would have it internally balanced. Not sure if this is. It has a externally balancer on it. I am going to put all new gaskets on it. When I have the heads & oil pan off is there a way to see if it is a stroker ?
