Is this a 727 or 518? I am assuming you are driving it on the street.
225# fixed line? Plan on replacing the direct drum or its piston as they will break.
It will not shift properly at that line without extensive moifications, so plan on setting it up for full man shifts.
The pump and any iron rings will soon be destroyed.
Converter? Hmmmm...
Time to talk to experts in the hi-per field with chipped up diesels. I would contact Goerends.
