$50 Craigslist 360 EXTREME budget rebuild??

It might be okay it was pretty or oily. Heck I'm already looking at some main bearings I had for the Stroker it was the number 5 bearing that didn't have the groove or the whole it had tube solid bearings two bottoms no top. So I look at Summit of course for at least a reference and the only thing they seem to sell is .010 under? Wouldn't I need stock bearings or do I need to have the crank turned down?
And good Lord if so how much is that?
