It looks like 4 3/4" bore and 6" stroke to make 638, 4 7/8" bore and 5 3/4" stroke to make 644. Have block bored for bigger sleeves, custom pistons and maybe different rods, it would probably be a good idea to get rid of stock cam driven oil pump and run an external one. How new of a 404 block is it? What type of injection pump are you going to run?

use a 466 crank driven pump block. your 404 will break and you have to start all over and spend all your money again.
