1948 Cockshutt 30 Engine Rebuild/Puller

I have a Cockshutt 30 that I restored a few years back that ran/runs real good but found out a couple years ago that she is a little down on the power end of things, dyno 18hp I think. Anyways its a good parade tractor and I am thinking about freshening up the ol girl and figured if I am going to do it I want to attempt to make it a stronger puller as well for 3,500-4,500. I don't pull a lot currently, 3-4 times a year with a few other tractors, but with my daughters getting older with tractor interest and wanting to be more involved I figured it is time to look at getting a couple more tractors up to par. I mostly run stock to improved classes on smaller pulls so I am not looking at going real big but would just like a good strong consistent setup that I can play with weight placement using my 13.6 tires. I know I have seen some guys on here that are good contacts and probably have what I will need so I am hoping they can chime in.
Here are my thoughts and questions
-Overbore Kit?
-Little bit of head work
-Should I do anything with the Cam?
-Is there any governor work recommended, to me it seems a little sluggish but haven't had much for engine loads on it
-It seems like I have a ton of throttle movement before getting much power so is that normal?
-Obviously I will be looking at the distributor as well as if I need to do anything different with the Carb

Any help would be greatly appreciated and maybe it could be a winter project that the kids can help with if I am lucky.
Thanks in advance
 
This is just thinking out loud. Your little motor is like 153 cu in. Worse is 6 to 1 compression ratio. A sleeve from a 756 IH is 3.875 . Yours are 3.4. .475 larger almost 1/2 inch larger. Your stroke is 4.125. I would think 5" would swing with a little grinding maybe more. You would have 235 cu. Dodge 4.7 v8 pickup pistons are this size 3.875. Piston pin is about right distance for stock rods. I think. Your compression will be about 13 to one. For a cam I would recommend competition cams. Chevy 350 camper towing grind. Memphis Tn. Find a speed shop with a flow bench. They should have a program to put in cfm of head .cam profile .rpm etc. And tell you your hp. Should have 80 to 90 hp. At 2800 to 3000 rpm. This is just adequate to pull 4000 lb at 4 mph. Is better for 3.5 mph. These are just thoughts not guaranteed to work. I have spent hrs. Looking for cheap ways to make motors powerful.
 
Well that is an avenue that I didn't really consider too much. I was thinking of just getting it a little over the 30hp stock or if possible around 40hp but now this intrigues me.
Thanks for the reply
 
A 175 Allis Chalmers engine will fit pretty easily and have condsiderably more power,also there was a 182 Buda motor which is the 4 cylinder version of the
273 Buda that would up the HP.
