Machine Work Required for Forced Induction

I'm planning to send a 1976 360 block to the machine shop to prep it for a build to include EFI and a turbo. Any special work need to be done (drilling oil passages or 4-bolt mains, etc.) that I should make the machine shop aware of? This is the first of many questions I'll have as this build-up takes place. Thanks in advance for the help!
