360 4-speed manual transmission?

To resurrect an old thread instead of starting a new one will a '73 360 be drilling for a pilot bushing? I have a chance on a '73 360 with a few goodies installed but I need it to go in front of a 4 Speed. Ive just took delivery of a 1980 360 from a Motorhome but not had a chance to check it out yet as Im working away from home.
