Tom has excellent information and advice.
As far as oil types the old 460 will be happy with almost anything slippery. I believe 10W30 was original fill. I run Delo 15W40 in my 460 just 'cause I like it. Trans fluid was originally speced for Mercon/Dexron and that will work just fine but Ford did update in a TSB to Mercon V (five) which is a semi-synthetic, but to get any real benefit from it you'll need to do a full drain which is hard unless the torque converter has a drain plug. Many don't!
Don't forget to flush in fresh brake fluid as well.
