So, I just bought this off of a buddy of mine, he doesn't have the time or funds to complete it like he wants. I paid a whopping $300 for it, the only problems being that a) the interior needs to be completed, and B) There's a crack in the block. The head is new, with some kind of aftermarket cam which a slight lope to it. Anyone know where I can pick up a 22R or 20R bottom end? I checked pull a part south, but they were long gone out of eveyrthing that would have had them. One pic is when he got it, the other is as it is now.
