bore it stroke it mill it and blow a wad of $$$$$ it will pull . farmall or moline is a better choice for the money , as far as parts for HP go. a DC takes alot of work
 
Yeah, I agree with X-treme, case parts for power aren't easy to find and are big bucks. Farmall's and John Deere's have many, many parts out there for HP upgrading. Doug N
 
For Farmstock classes, 3 to 3.5MPH, they don't need extra power most of the time. If you want to go into the faster Open classes, go to a later model Case or switch to Oliver, Moline, or Farmall. Parts are more popular for those. Any way you go, "Open", "Fast" and "Money" are synonymous terms.
 
It can be done, and yes it is expensive, but so are all the others. The molines aren't as cheap as they used to be because everyone is doing them now. I made a DC go fast and it had lots of power and it was fun, but they can't compete with the 6 cylinders in open classes. MPH classes on the other had, they can be made to compete in them. Mine pulled in a 5 mph class and it did very well.
 
Honkey tonkey stompey stompey, clue in buddy get a "L" case from someone that knows what they are doing, obviously you don't!
 
the "REAL" people who know how to get power of these are not going to give out secrets on here. we are getting over 70 hp with stock stroke, small over bore and alot of little things, in low gear farmstock classes these are hard to beat if they can get traction.
 
I rolled out a stock stroke big bore DC this spring for my cousin, while I understand that this forum will lay still for anything put up here by anyone , it ran an honest 110 hp at 1400 rpm on a m&w dyno without ANY break in time whatsoever. 1380 is the hi idle on this engine stock. I think that Travis will vouch for my honesty as I helped him with his DC project. This tractor is DOMINANT in this part of Penna, The expensive part was the pistons but if I could get what the engine builders in the midwest get for a competition engine I would build them all day !!!! Build instead of buying everything and a DC can be built VERY cheaply. Sincerely mEl
 
That"s what I"m saying too. In Farmstock, a DC Case don"t need much at all done to it. Open classes are a different story. You better have a lot more than 70hp, or 110hp, for that matter to keep up with big boys in the Open classes. It doesn"t matter if it"s 5mph, 8mph, or 12mph. If it"s Open, you better have BIG horses and lots of "em. If someone is dominating Open classes with 110HP, there must not be much heavy competition.
 
Lamont, The area that we pull in for some reason has resisted NATPA classification of tractors, the forementioned tractor is stock appearing , the only concession being electric w/p and fan. It is ,of course not competetive in a true open scenerio, but will handle itself quite respectfully in speed limit classes especially up to 6 mph. You are right on about the massive HP required for true open class pulling, but our area is somewhat behind the midwest in the quantity of those type tractors. My point was that with minimal work- block boring, making sleeves from readily available stock CASE sleeves, and the right choice of available pistons, a good cam grind and some port work on the head a DC will make a lot of power. WE do as much of our own work as possible, holding the cost way down, not all can do that!!, mEl
