360 block help thank you

OK wait'
what would be the point of boring a 360 to fit 340 pistons and then installing a short stroke 318/340 crank, on spacers I'm guessing, or a big journal crank?
Not too many years ago; we used to read about this all the time, and a friend of mine, whom I have no reason to doubt, claims to have done this exact thing; namely 340 pistons into a 360 with the 360 crank, and open-chamber heads. Yes, he owned a machineshop at the time, 20 years ago. And yes it was quick.
However,to be accurate; I did not see the project go together.
In today's market, I don't see this as in any way feasible. Do-able yes. But there's way cheaper, and far better ways to rebuild your 360.
The cheapest way I have seen; is to just slam the tallest hypers in there on bushed rods. Done deal,you can take it apart as often as you think necessary, with re-useable gaskets.
My KB107s came in at .012 below deck. Add an .028 gasket and a closed chamber head and yer done. If you have to clean up the decks, then cut her to zero and use the FelPro .039s. Depending on your total iron chamber volume, cam selection may be troublesome. With alloys, give her to the max.
