How can I find out the difference between the different transmissions? For instance, does a700-070a have steel gears? Fine spline output shafts? How many shift keys? Or a 700-079, 700-083?
  Thanks, Kevin

The #s on the case isn't a guarantee of what's inside. Sometimes they have been rebuilt & the gears replaced.

700-078A is a coarse splined transmission, but I haven't found a PDF
with the part number for that shaft.

Is it necessary to change the gears to get certain gear ratios needed for racing or do most guys just run them with the gear ratios they come with?

Most run them with the gears that they come with. You want to find the 1:1 gearset in the tranny which is 25/25 tooth. Some use different gearsets but that is the most preferred.

Do racers do a pulley swap for larger pulleys or anything of that nature for the drive line?

In short, yes.  Primarily a 6" or 8" under the engine, and 4" or 5" under the transmission/transaxle.  There are many size steel pullies to dial in what you are looking for, but the aforementioned sizes are the most popular.

EC distributing sells outstanding pullies in the billet aluminum flavor, and are made specifically for the "A" belts.  To experiment with different pulley and sprocket combinations, go to EC's website and click on "Technical Info", and under that, "Mower Speed Calculator".

IT ALL DEPENDS ON THE ENGINE. EVERYONE HAS GIVEN A GOOD STARTING POINT. YOU WILL HAVE TO TWEAK IT AS YOU GO.

  Steel bevel input gears Addendum:
   The short Steel Bevel Input Gear that uses the needle-style thrust bearing between the gear and the case is Part Number 778176.
   The needle-style Thrust Bearing is Part Number 780071, and the Thrust Washers on either side of the bearing are Part Number 780072.

Respectfully,

I know this is old but wondering if there is a way to tell if you have a steel bevel gear by looking at it?  Have a couple short bevel gears and am building an all steel 700 with bearings and want to use the thrust washer setup, just want it to be steel
