About half way down the page.

On another note, the rods are the same, the pistons in the 64 are bigger, and the cranks can be interchanged BUT it will change the stroke length. 63 stroke in 64 block lowers it from a 2.4, and a 64 crank in a 63 block raises it from 2.0 to 2.3.

Not sure what else you want to know. The 63 head bolts to both.

If you put a 63 crank in a 64 block you will need pistons with a 6mm lower pin height OR 6mm longer rods due to the 64 block being 6mm higher than a 63 block.
