870 to 871 engine swap in my 2007 international 9400

The second option is for sure the only route to go if he plans on using it. The 870 is out and can be overhauled easily. Tell the asshat that sold him on that business sinking butchered 871 that he's not paying for it and get it out. At least then he's only out the time spent to pull an engine out of the truck. When its done he'll have a reliable "can sleep good at night" over hauled cm870 to make $$ with for the next million.
