I got mine with a spun bearing for about $450. I figure prices like that are too hard to pass up. I was planning on totally building one anyways, so replacing all the internals with a 392 stroker kit is no biggy as I was already planning it. The heads will also be worked and a new cam put in. All stuff I was already planning on doing.
So in my opinion as long as you have a good block, heads (these can be bought if bad), and intake and wiring you're all set to have a powerful working modern hemi.
