There is a Reason, Even though the Blocks are all same outside dimension the 326 and 350 blocks cant go to the same cubes as the 400+ Blocks. Not sure the specific reason.
One reason is that the cylinders weren't cast to the same size as the larger engines. (They can't be bored enough to put 400 pistons in them.)
