OK, So I am excited now that I might be able to drive over to Dad's and put a chain to his 46 or 37 G. No bore, and I think ~ 38-40 horsepower.
Good grief, now the juices are flowing. Is 50 HP within easy range, or, are stepping into money and more radical upgrades (kindof makes me think that at some point, you have to consider the crank and rods durability)
So, this is what I just digested from your comments, and a few more questions if You don't mind.
1. High Compression pistons and gas manifold.
Question: Going higher compression, leads me to think that I will likely be advancing timing. If I remember correctly, timing on the ol g is 25 deg BTDC. If this is true, can I do it by ear or to truely dial it in do I have to find a dyno somewhere?
2. Distributor: It has a mag on it. Is the switchover easy (bolt up) to current governer body, add coil, etc? Is this a common upgrade?
3. Water pump: Our ol G's were notorious for overheating (even on Tractor fuel!), no real surprise here. Is this also a common upgrade wherein I can find an upgrade kit and simply bolt on the pump, add the pulley, and modify the cold water return? I just tried to find this kit, and I must be lame in my searching.
4. Are these types of upgrades the types of things You would do even if You were not going for much more horsepower, but just to take advantage of current fuel, technology?
I plan to keep this tractor in the family from here on out. Want to stay close to originality, but not completely married to it. I want to have fun and work it a bit (work on these = fun from me).
Thanks again, to all of You for your comments, in advance.

Today's Featured Article - Tuning-Up Your Tractor: Plugs & Compression Testing - by Curtis Von Fange. The engine seems to run rough. In the exhaust you can hear an occasion 'poofing' sound like somethings not firing on all cylinders. Under loaded conditions the tractor seems to lack power and it belches black smoke out of the exhaust. For some reason it just doesn't want to start up without cranking and cranking the starter. All these conditions can be signals that your unit is in need of a tune up. Ok, so what is involved in a tune up? You say, swap plugs and file the points....now tha
