I have much the same question as the Winebago one. I have a 440-1 engine in a 78 25' motorhome. Mine has the van front on it. I have added ceramic coated headers with racer rap on them, electric cooling fan up front and just recently a major tune up. I am trying to find out the horespower and torqe rating for this engine and what else I can do to it to get a little bit more performance without compromising reliability. |
