Questions about the Mopar Performance 340 Replacement Block P5007552AB

Yeah but doesn't this say all production 340 parts fit? and no the blocks are rough bored and you need to have it finished to match whatever pistons you want to use. I think you can actually order different rough bore sizes too. Here is a new listing here at FABO for 340 short block for 650 bucks.

Just read this build using the block you are asking about has the required machine work needed and sounds extensive to me but good read for you. Hope this helps.
