Perhaps starting off with a more solid foundation is worth considering.

That is the price of the block. It still need bore/hone, decking and maybe the mains sized so it's definitely not within a $1000 all said and done. I would still go aftermarket block over a done stock block with everything since you will have plenty of room to grow and will always be way stronger.
