the blocks are interchangable, you'll want the oil pan and stuff, if you use the head off of your engine it'll all work with your intake and stuff... there's a spot for the distributor in the block.
the only difference is a little bump on the bottom in the engine crossmember area on the drivers side I think. if you have a 4x2 and end up with a 4x4 pan you won't notice a difference, the pickups are the same, it's just a clearance bump...
