Nope, no issue with your tractors. Just trying to demonstrate the limitations of the F226. It is not the be all, end all that you make it out to be. Whether you would like to admit it or not, it takes serious cash to get 100HP out of a F226 engine (at stock +20%).
I know what it takes to get that out of a 4 cylinder and the flathead aspect of the F226 makes it more expen$ive. My point is that the money spent on the F226 to get 100HP would nearly "buy" 150HP on the H260...
That is all.
