The other day I thought I wanted to trade my Ford 641 to a little more modern tractor. After looking around, I decided that mine was probably just as powerful, and probably in better shape than most of the ones I looked at. I've found a rebuilt steering box for $150, and I'm getting some new rear rims, and getting around to fixing a few things that I had let go. After that I'm going to slap a new coat of paint and some decals on it.
Now to my question. A few years ago I ordered a 3.5" overbore engine kit from here and installed it on my tractor. I believe this is just a little bigger than stock at 3 7/16". TractorData lists the stock 641 at 48.4 hp. Does anyone know if the upgrade makes any appreciable difference in horsepower?
