If it's a small block it's more than likely a C-4 and if it's a big block it's probably a C-6, depends on whats been done to it over the last 38 years.
My general rule is if your mechanically inclined, can read a book, are organized and methodical, you can do anything!
Having said that, an automatic transmission has alot of parts in it. From your initial questions and the simple fact that you have to ask what transmission you have (and please don't take this personally, I really don't mean to make this sound nasty or put you down, I'm just trying to get you thinking realistically) I would say tearing a transmission apart would not be in your best interest. You could always pull it out and take it to a trans shop and then re-install it, that would save you some money.
Shop around on trans shops too. Prices can be all over the place. If it's real low, make sure to investigate what they will or won't be replacing for that price and what "extra" parts may be tacked on after they start. Check for references and maybe the BBB.
Also what rear gears do you have in the car and what are your plans with the car down the road. What cam do you have and what is your rear tire size. The reason I mention this is that a good trans shop will always have you replace the converter when they rebuild the trans and if you do that you may want to buy a converter with a little more stall. They'll want to know the above questions. More stall will give you a nice "take off". Be realistic and don' t get carried away though.
And remember, before you do anything, it may be worth a tow to a trans shop for an inspection. Sometimes a "no go" can be a very simple issue!
