My friend wants to do a stroker motor with a 400 block. I have a 440 crank and rods. Is it better to align bore the 400 block than cut the crank down? What is the going rate to open up the 400 mains to accept it and how much does it need to be opened up? Do the 440 rods have any clearance issues? Which pistons should he go with?

Is there a guide out there somewhere when making this setup to go by?
