I thought the same as well but decided that I would rather build a 727 and not worry about what I do with the stroker later.
As for the 360 itself, like you said there's not much I will need off of it besides the block but there's that plus all the other things people don't think about until they go to assembly. Timing cover, oil pan, accessory brackets, pulleys and more. Hell, even having all of the bolts might come in handy.
With all that being said, I think the $300 was well spent. In fact the seller even dropped it off to my engine builder (20 miles away) for me so I didn't even get my hands dirty. lol
