The ford V10 is a very well built power plant
But the 302 V8 gets too hot powering a PTO it needs to be moving to stay cool. The Butler corp wont tell you that but some of there sales people will. You need too ask Butler wy they dont install in a powerstroke..
Our E-350 with the 5.4 can easily handle 115 degree Vegas heat all day in the summer. But it does have a aftermarket grill. It also has actual and equivalent miles of 500,000
