Just wondering theo1963 , what did you do? Did you convert to high output, or what did you find out? Let us know.Hey theo1963 one way to tell what it might take to convert to high output is to go to CNH website. Click on construction equipment on the lower left. Click on search for parts and or launch parts catalog. Type in 430 in the window. Click on the the best selection that fits your equipment, and start comparing factory part numbers of pumps, valves ect. Believe me it sometimes is easier having a second computer to compare part numbers to convert.
