The blocks have the same dimensions. The 427 crank(3.76 stroke) will work as long as you use the pistons for the 427. The 454 crank (4.00 stroke) will require the 454 pistons. The rods are the same. If you used different length rods then you would have to use the right pistons for the custom rod length.
