I went through and rebuilt the cylinder head and did some port work on it also. Between doing that and the manifold, when I took it out and pulled with it after doing the work it was a different animal. I am not sure how much HP I gained. I also bumped the govornor up to 2100. I am guessing I am close to 30HP. Pretty good gain from the 23HP. The head I put on and reworked is also off a C. The original super C head was cracked.
Farm stock class allows anything as long as the outside is stock appearance.
Should do more derby videos
Did you do any other work for the tractor? How much horsepower did you gain?
