Will a Stock 489 handle 700hp?

@70DusterBob, he built it from a truck dana, probably started with a core, for around $250, then had it narrowed, new axle ends, custom axles, and a suregrip, or spool, around 800 in parts, and a couple hundred in labor. For guys that can do their own narrowing/welding, i have heard of danas done for under a grand.
