Question about the price of 340s

So I guess that if I wanted to put a stroked small block in my Barracuda, I'd be better off selling my good running 340 and building a 360 based motor as opposed to having the 340 built. I don't care about originality, and it sounds like the 340 is worth enough to offset some of the stroker cost.
My 68 Barracuda has a stroked 1968 340 block in it. Now a 416. Changing one back to a 340 isn't that big a deal, unless you trash the block.
