Unfortunately, it isn't that easy. This would require sleeving the block, otherwise, the cylinder walls will get too thin. The castings are different for each block because the bores are different.

If you want power, your best bet would be to obtain a 351 or 401 with a 6 bolt flange (if you want a direct swap into a pickup)
